• Internet Explorer not working after establishing a SSTP VPN connection

  - by Massimo

  I have a problem which is constantly appearing on each Windows 7 computer I'm using, whenever I establish a SSTP VPN connection to a ForeFront TMG 2010 firewall; it only happens with SSTP connections, not PPTP/L2TP ones. The problem appears only if using a proxy server for Internet access; it doesn't happen when directly accessing the Internet (with or without NAT). It doesn't seem to depend on a specific proxy software being used (I've seen it happening with various ones). The problem is: as soon as I start the VPN connection, Internet Explorer can't access anything anymore. I'm not using the VPN connection as a default gateway, and I can succesfully ping the proxy server after the VPN connection is esatablished (and even telnet to its 8080 TCP port), so this is definitely not a routing problem. Also, the problem is specifically related to Internet Explorer: while it seems not able to connect to any site, other programs (such as FireFox) have no problem accessing the Internet through the same proxy. This behaviour can be easily reproduced on any Windows 7 computer (the service pack and patch level doesn't seem to matter at all). Have IE connect through a proxy, establish a SSTP VPN connection... and IE will just not work anymore until the VPN connection is dropped.

• How to determine the root cause of a system lockup on Ubuntu 8.04 LTS?

  - by jdt141

  I'm currently working a project that involves setting up a PC/104 stack and running Ubuntu 8.04 LTS. We need to use the PC/104 stack because its an embedded application - and we're required to use a DeviceNet peripheral card to communicate to other devices. (DeviceNet is just a protocol on top of CAN.) Anyway, the following hardware is on the stack: Kontron MOPSPM104 with a 1GHz Intel Celeron processor ConnectTech FlashDrive/104 4GB Industrial Temp (-40 to +85 C) Woodhead (Molex) PC104DVNIO DeviceNet card A run of the mill 104 power supply The Kontron Board offers two serial ports, one VGA out, and two USB ports. The DeviceNet card is an ISA card. Because of this (per the User's Guide for the Kontron Board), I have manually set the IRQs in the BIOS to be appropriately configured, and turned off ACPI in both the BIOS and passed the appropriate flag in GRUB. I've installed Ubuntu 8.04 desktop, 32 bit. The problem that I'm having is that, from time to time, the entire 104 stack locks up. This only seems to happen in two cases, both of which we're running GNOME. We have a custom application that uses the DeviceNet card, and the system will lock up, or (more frequently) when we're running Firefox and either surfing for some information or trying to test it - typically by streaming video from a IP-camera. The reason I ask this questions is I cannot determine the root cause of this lockup. The IRQs appear to correctly configured in the BIOS and as the Kernel sees them, and nothing is logged to dmesg. If you all could help me determine the root cause of this lockup, I would greatly appreciate it. Thanks.

• Ubuntu networking issue: two specific machines cannot browse web while connected to network at the same time.

  - by jensendarren

  I have setup a secure wireless network which works very well except for two laptops running Ubuntu 10.10 that can't access the Internet via a browser at the same time. They can both ping sites, wget sites, use skype but when using a browser the page never loads (in Firefox the status bar just sits there saying "Connecting" until it times out.) Here is what we have tried so far (nothing has fixed this issue): OpenDNS Restart networking services Using wired connection rather than wireless Removing all other nodes from the network except the two machines that have this issue Swapped out the router Factory reset the router Reformatted one of the machines and re-installed Ubuntu 10.10 Other things that we have checked: The two machines can connect simultaneously without any issues to other wireless networks in different locations (say in an Internet Cafe or another office) The two machines have unique IP addresses The two machines have unique MAC addresses The two machines can communicate on the network using Skype, wget, ping etc We are not using a proxy on either machine FYI: I have attached output from wireshark. For the test we turned both machines on and pointed them both to the same website. The content loaded on one and not the other. Here is the output from wireshark- (speedyshare.com/files/26228631/machine_output_1 && speedyshare.com/files/26228649/machine2). As you can see the first one worked, the second one didn't. I don't fully understand the output and would appreciate if someone could shed some light on what might be causing this and how we can fix it! Many thanks! Darren

• Client unable to access OWA website after temporarily changing SSL certificate on the server

  - by Lorenz Meyer

  I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

• Reduce "Metafile" memory usage?

  - by Jay Conrod

  My work computer (Windows 7 64-bit) spends a lot of time swapping memory when I switch between programs. This surprises me since I have 4 GB of RAM, and the programs I use aren't particularly RAM hungry (Outlook, Emacs, p4win, Firefox, various build tools). I downloaded RAMMap, and it shows over a gigabyte of memory used by "Metafile". From the Sysinternals blog: Metafile is part of the system cache and consists of NTFS metadata. NTFS metadata includes the MFT as well as the other various NTFS metadata files. ... In the MFT each file attribute record takes 1k and each file has at least one attribute record. Add to this the other NTFS metadata files and you can see why the Metafile category can grow quite large on servers with lots of files. So I understand what the "Metafile" data is... I work on large builds comprising hundreds of thousands of files (none are that big, but they add up to several gigabytes). My question is how can I reduce the amount of memory used by "Metafile"? I'm not actively using all those files at once, so why does Windows need to keep info in RAM? Restarting my machine every time I sync a new build is really annoying.

• SVG doesn't work on subdomain - some browsers try to download rather than display

  - by John Catterfeld

  I have a site with a 'development' subdomain, which displays my SVG file exactly as intended. However when I copy it across to www, or any other subdomain (e.g. 'test') some browsers try to open the file in an external editor, therefore asking me to download the file rather than displaying it. For example: http://development.mysite.com/test.svg - works http://www.mysite.com/test.svg - doesn't work The SVG file: <?xml version="1.0" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red" /> </svg> This happens in Firefox, Chrome and Safari, however IE9 and above display the file as intended. It is a Windows hosting, and I have <mimeMap fileExtension=".svg" mimeType="image/svg+xml" /> in my web.config file My hunch is that there must be some setting on the server which I need my hosting company to make. Can anyone suggest what might cause this issue?

• What is causing ocassional white windows on my Mac?

  - by user63333

  Hello. I'm having a very strange problem with my Mac lately. When I'm working in an app and a new window pane or sheet is displayed, sometimes it comes up completely white. Once an app is having these problems, it will continue to bring up a blank screen for that particular window (although other windows work fine). After the app is relaunched, the window is fine again. What I'm noticing that's very strange is that although the interface turns completely white, the functions of the interface are still available. So I have to "navigate blindly" around the interface, until I can relaunch. This occurs throughout the operating system. Screenshots: This is what happened when I tried opening the File menu in Lightroom app. What happened to me on Lynda.com (in Firefox) after selecting the "Software..." dropdown. (All other dropdowns were fine. Reloading the page fixed it.) When I was decompressing a file, The Unarchiver launched and opened this white window. It still decompressed the file. This is what happened one time when I opened Finder (with TotalFinder) to my Downloads folder. This is something I've never seen before. This just started happening lately. What could be the problem? Thanks for your help. NOTE: since new users are not allowed to post images, just image blank white interface elements. And since new users also aren't allowed to post more than one link, here's the first screenshot:

• Redeploy using Active Directory

  - by Noam Gal

  I am trying to use group policy to deploy our msi through AD. For some strange reason, when I overwrite the msi with a newer version, and then go to the policy, and click on "Redeploy Application", the application gets uninstalled on the users' machines, and all reg keys, binaries and shortcuts are gone from them. The "Add/Remove Programs" still contain the application entry. I have managed to create a minimal vdproj that does nothing but write its current Product Version to a registry key, and created two versions of it (1.0.0 and 1.1.0). I still face the same problems when using this msi in my AD environment. I did check that my Package Codes and Product Codes are different for both versions, and that the Upgrade Codes are identical. I also checked the RemovePreviousVersion to true. Checking with some other msi (firefox 3.0.0 and 3.6.3) I downloaded from a site specifically for AD deploy, it worked just as expected (first installing the 3.0.0, then I over-written the msi, and clicked on "Redeploy", and the users got 3.6.3 after the next log-off-log-on). What am I missing here?

• Why is dwm.exe using so much memory?

  - by Leonard Challis

  I've scoured the web, but I'm sick of reading "scan your computer for viruses" and "upgrade your RAM" on answers to similar questions to this. I understand that dwm.exe is for (simply put) caching bitmaps for things like Aero-peek and similar, but as far as I have read it shouldn't be using vast amounts of memory. My colleague and I both have 4GB of RAM, Core 2 Duo, blah, blah -- essentially they're pretty capable. His dwm.exe is running at around 30mb, mind is currently running at about half a gig, though it does fluctuate quite a lot. This is the same while running the exact same applications (currently Zend studio, FireFox (with firemin - low memory usage), Outlook). Every so often I will get a notification asking me if I want to switch to Aero Basic because it's using too much memory, and sometimes it will just switch itself to basic and let me know why. I know it's possible to stop it switching, but I want to know why it is using too much memory otherwise it's just papering over the cracks. One thing to add is this seems to have started after a robbery on Monday, where two of my monitors were stolen, and I had to temporarily use a couple of alternative monitors. I am now using brand new monitors but the problem is the same. All drivers installed and working seemingly fine. Any ideas why the usage is so high? We are using windows 7 64-bit Professional.

• Links break in IE9 when using Wordpress plugins in non Wordpress Page

  - by mouli

  I have a site that uses SEF URLs and htaccess RewriteRules to serve up the pages. This has worked fine for several years until the arrival of IE9. Now it appears that the links are not being rewritten and the site is dead in the water. I have tried different compatabilty modes, to no avail, and I've played with the Rewrite Rules over and over, tried different doctypes and a few other browser settings. I agree that it cannot in theory be a browser specific problem if the problem is with the htaccess file but this site works in IE8, firefox and chrome. I have run the rewriterule through a validator and it looks fine. Any ideas would be appreciated as I am running out of ideas. The site is www.marlboroughsounds.co.nz a sample link is http://www.marlboroughsounds.co.nz/walking/freedom-walk-queen-charlotte-track/4dfw and the rewrite rule thats not working looks like this: RewriteRule ^walking/.*/([a-z0-9_]*)/?$ /walking.php?act_code=$1 [L] The link fails and it serves up a browser 404 page, not even the custom 404 I have for the site. Any ideas would be much appreciated as I am stumped.

• Virus cleanup; Windows Automatic Updates service crashes in esent.dll

  - by quack quixote

  Background I'm doing system recovery on an old WinXP SP1 system brought to me on suspicion of virus infection. After taking preliminary backups, I used MalwareBytes to detect and clean the infection. I might've even gotten it all. In the process, I've discovered (a) the system drive is showing signs of impending failure, and (b) the owner has been using the system's old crusty IE-6 instead of the up-to-date Firefox I've provided for him. So naturally, thinking I had a relatively stable system, I tried to hit the Windows Update site to install IE-8, in case further training doesn't stick. The update site told me it needed to update the installer, and I started that process. Soon after, wuauclt.exe started crashing, reporting addresses in module esent.dll. There's a Microsoft KB (910437) on a problem with that DLL, so I downloaded the hotfix and installed. The crashing did not stop. I attempted to install SP3 from the offline installer, but that didn't fix the issue either. The system is reporting a few hard drive / IDE controller errors, but they don't correlate to the crashes, so they aren't the direct cause. I've also attempted to rollback to the time between the infection removal and the first crashes, but that doesn't help. Question The hotfix I tried to install dealt with problem in transaction logs of the Extensible Storage Engine (ESE) database. I suspect this issue is similar, but that the database itself (whatever the ESE database is) is corrupted. Is there a way to clean or clear this database so that system operation returns to normal? Can someone enlighten me as to what the ESE database actually is, and where it resides? Can I just locate some files and delete them to bring this under control?

• Windows Vista Wrong Certificate With SNI

  - by JamesArmes

  I'm setting up SNI on an apache server and I thought things were going well. I have two URLs from different domains that point at the same site. I have one virtual host setup for each with the appropriate certificate for each. One of the certificates is valid but the other is self-signed (waiting on GoDaddy for the real cert). If I test the different URLs in Firefox, Safari and Opera all works well. I get no errors for the URL with the valid certificate and I get a self-signed warning for the other. However, in Internet Explorer 8 and Google Chrome, both URLs return the valid certificate (even if its not valid for the specific site). So for the one site, I get a valid certificate. For the other, I get a warning about the cert being for a different site. I tried switching the order of the vhosts and it made no difference. I know that Chrome and IE both use Window's HTTP stack so I understand why the behavior is the same for the two. What I don't understand is why I'm seeing this behavior.

• Chrome pop-up blocker fail?

  - by Count Zero

  I have this problem since just a few days. I've been a heavy Chrome user for several years, but it never happened before: Sometimes absolutely uncalled for pop-ups appear, when I click something absolutely legit. It seems to happen at a very precise rate of two pop-ups every hour or so. The pop-ups are not very varied, it seems to be a fixed set of some 4-5 ads. At first I thought I caught some malware, but after a full scan with Malwarebytes Anti-Malware, I found absolutely nothing. In addition the problem exists only with Chrome. When I use Firefox, this never ever happens. What is even more puzzling is that it happens on both of my rigs and started on the same day. I have a removable storage that I dock to both of them and access one machine from the other via RDP, but still... It seems this is a problem that others face too. See this Google forum and here. Could it be that the latest Chrome build is just acting up? (Just in case it matters: I run Chrome version 24.0.1312.57 m on Win 7.)

• Wireless very slow on one laptop on network, all other machines normal?

  - by th3dude19

  My new laptop (Acer Aspire Timeine 3810TZ running Windows 7 Home Premium 64bit) is acting very strange on my wireless network. Below are the issues I'm noticing... The connection frequently drops. I see the icon change from 'full bars' to 'empty bars with yellow star (meaning no connection)' occasionally. Almost every website I visit (Firefox) hangs for a long time on 'Looking up www.amazon.com' for example. After a long pause, it finally starts loading the website. Neither of these problems exist on any other machines on my network. I also have a desktop running the same OS wirelessly and it works fine. I've run several Speedtest.net tests and the speeds are great (20MBit down/4 up). Results from pingtest.net are as follows: Line quality: D Ping: 46ms Jitter: 65ms Packet Loss: 9% These results are to a server that is less than 10 miles from my residence. The results on the other machines in my house are normal. Any suggestions? This is becoming very annoying as I purchased this machine primarily for browsing.

• Pages load in brower fine, but 404 not found reported for the page during the GET on all pages except index

  - by user885983

  I believe this question is more suited to serverfault (please correct me if not). This issue appears very similar to this question (except there are no 301 Moved Permanently for any pages). The domain is yorkshirebadges.co.uk. For example, loading yorkshirebadges.co.uk or yorkshirebadges.co.uk/index.php reports no 404s during network inspection. But every other page (/contact.php, /products.php) report a not found. Mod_rewrite is being used on the site, I checked this out but didn't see any obvious errors. It's included below for reference: RewriteEngine on RewriteRule ^store/material/([^/\.]+)/price/?([^/\.]+)?$ products.php?prodType=$1&price=$2 RewriteRule ^store/price/?([^/\.]+)?$ products.php?price=$1; RewriteRule ^store/material/?([^/\.]+)?$ products.php?prodType=$1 RewriteRule ^store/([^/\.]+)/?$ products.php?prodCat=$1 RewriteRule ^store/([^/\.]+)/price/([^/\.]+)$ products.php?prodCat=$1&price=$2 RewriteRule ^store/Type/?([^/\.]+) products.php?prodType=$1 RewriteRule ^store/([^/\.]+)/?([^/\.]+)?$ view-product-details.php?cat=$1&prodName=$2 RewriteRule ^store/([^/\.]+)/material/?([^/\.]+)?$ products.php?prodCat=$1&prodType=$2 RewriteRule analytics http://www.google.com/analytics <IfModule mod_suphp.c> suPHP_ConfigPath /home/yorkshir <Files php.ini> order allow,deny deny from all </Files> </IfModule> Chrome Network Inspection (and firebug on firefox) report 404s on all pages except the index, the server is apache2.

• Windows Update and lsass.exe

  - by David

  I have a brand new installation of Windows XP (SP1 or older). I installed Norton AntiVirus, Firefox, Putty, and Cygwin. No other software is present. Windows Update finds the following 64 updates: KB905760, KB978262, Internet Explorer 8, KB71961, KB954155, KB968816, KB923561, KB950762, KB949402, KB950974, KB951376, KB951748, KB952004, KB952954, KB955069, KB956572, KB956802, KB956803, KB956844, KB958470, KB958869, KB959426, KB960803, KB960859, KB961501, KB969059, KB970238, KB970238, KB971032, KB971468, KB971657, KB972270, KB973507, KB973815, KB973904, KB974112, KB974318, KB974392, KB975025, KB975560, KB975561, KB975713, .......) When these updates are applied, the system reboots to a black screen with two error messages. The first error message says: lsass.exe - Application Error The application failed to initialize properly (0xc00000142). Click on OK to terminate the application. The second error message says: services.exe - Application Error The application failed to initialize properly (0xc00000142). Click on OK to terminate the application. I then proceed to boot into Safe Mode, use System Restore, and everything works fine again until the 64 updates re-appear in Windows Update. I can see two options: disable Auto-Updates or install each of the 64 updates one at a time until finding the troublesome update. Does anyone have any better ideas?

• Apache returns HTTP 206 for GET /file.mp3

  - by javano

  I am making a get request to an SSL enabled site on apache (so wireshark isn't giving me anything to useful). In my Apache SSL access log I see the following entry: 1.2.3.4 - my.username [15/Nov/2012:16:52:01 +0000] "GET /uploads/file.mp3 HTTP/1.1" 206 534400 "https://site.com/uploads/layla.mp3" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.168 Chrome/18.0.1025.168 Safari/535.19" Why is this happening? I'm not familiar with the HTTP 206 response code but searching the Internet I can see it is a partial content GET requests. I understand correctly, my browser is making a partial GET request not for the full file. Is that correct? If so, is this a browser issue or is the web server instructing my browser to do so? I have tested in Firefox also and in both browser, I am not sent the file. If I rename the file to file.jpg I can download it through my browser and rename it to .mp3 and it plays. How can I troubleshoot this issue?

• Track kids browsing history even when they know how to clear it manually

  - by Darren Newton

  I have a colleague with two teenage boys (yes, cue cliche's about 'I have this friend see...') He's currently having issues with them browsing pr0n and wants to do a little spying on their browsing (I'm staying clear of the philosophies/ethics on this.) The kids are savvy enough to clear their browsing history when they're done. As I'm his goto for IT he has asked me if there is a way to keep a hold of the browsing history. The family uses Macs, and the kids surf with Safari. I know that browsing history is kept here ~/Library/Safari/History.plist. I figure there should be a way to write either an AppleScript or other script (Python/Ruby/Bash) that can backup this file to a different location (/opt/local/history, etc.) Since the kids know to clear their history when they're done should the file be periodically backed up with something similar to a cron job or something like Hazel? While that could work it seems like it would create a ton of little incremental backups. Or is it possible to 'watch' ~/Library/Safari/History.plist and incrementally add changes to a backup file (saving a diff so to speak) but not lose any data? Any ideas/solutions appreciated. UPDATE/EDIT: Got the word from concerned dad that the oldest uses Firefox on a different PC, so the OpenDNS solution (preferably at the router level) is the best answer so far as it would capture usage for the whole house.

• how to diagnose a hard system seizure? Dell+Ubuntu

  - by rob

  I've got Ubuntu 9.10 on a Dell Vostro 420 desktop, a little over a year old, which I use for plain vanilla work stuff (email, web, terminal, text editor). Every now and then, at totally random times, it completely freezes on me. Hard. Mouse and keyboard stop working, cursor stops blinking, clock stops moving. All I can do is hold down the power button on the front of the box to shut it off. Sometimes it happens after several months of continuous uptime; sometimes it happens a few minutes after a reboot, while all I've done is open a terminal to look at log files, or maybe firefox to do a google search. Each time, there is nothing at all in /var/log/messages at the time of the crash. This makes it seem like a hardware problem, and indeed a few months ago I opened the box and wiggled everything and the problem went away for a while. But now it's back. I went in and checked everything, took out each RAM card and reseated. No luck. I ran all the system diagnostics (the long version) and everything passed with flying colors. Something is messed up in this box, but without any useful logs or failed tests, how in the world am I going to find it? And of course, Dell's not gonna help me cause I went and replaced Windows with Ubuntu. What steps would you take next to track down this problem?

• win 7 something is causing excessive disk usage, maybe chrome?

  - by camcam

  On my Win 7 computer, this happens: I work for several hours without problems, also using Chrome Suddenly, just after refreshing a page in Chrome, disk starts being used excessively (here I can close Chrome or not, no matter, the disk won't stop) Disk diod is on all the time and I hear it running like crazy, all computer is a little slowed down It last 5-10 minutes In the meantime, I go to Windows Task Manager and observe what processes are using disk and turn them off one by one - but no success in stopping the excessive disk usage After approximately 10 minutes everything stops I go to Chrome (or re-open it) and refresh the page with mixed results - sometimes the whole process repeats immediately, sometimes not Basically, it is almost always Chrome refreshing random page that starts the excessive disk usage, but killing Chrome process does not stop the disk. Going to the same page in Firefox is not causing problems. Windows Search is turned off. I would like to know what is really happening. Perhaps there is a utility which would allow me to see which process is really using the disk, so that I can disable the service ? (not chrome, because killing chrome does not change anything) or even better, perhaps there is a way to fix it?

• can't get to admin page after factory reset netgear wg602

  - by stefanB

  I have wireless Netgear wg602 on my home network (connected to my internet modem/router). I've had it secured and locked down to only accept connection from specific MAC addresses. I've forgotten the password that I used but my Mac Book laptops can still connect (multiple OS updates - it can't retrieve and display the password but it can use it to log in to WPA) so I want to reconfigure it from scratch (have some new devices). I tried to reset the Netgear wg602 to factory settings (pressed reset button for 10 sec), reset my laptop IP address to local address suggested in manual (192.168.0.210 net mask 255.255.255.0), connect Netgear via ethernet cable to my mac book pro but I can't get to the admin page at 192.168.0.227 as suggested by manual (firefox or safari). At this stage the Netgear is not connected to router, it is only connected to mac book. I can't ping the wireless access point either (but it is on all lights are on). What am I doing incorrectly? Last time I configured it via Windows now I only have Mac Book (which I've used with the wireless access point for 2 years so no compatibility problems).

• Suspending/Screen Going Off When Still In Use (Ubuntu & Arch)

  - by luke

  I have a laptop (HP Pavilion G6) that was running Ubuntu and for a while now (at least 6 months) has been having a problems randomly suspending whilst still in use with a full battery and still being charged. Originally the problem was with Ubuntu so I first attempted to disable suspend using every way I could find (gui settings + dconf editor) this didn't work and it still kept suspending so I ended up switching to Arch Linux. Unfortunately not long after switching to Arch Linux I ended up experiencing the same problems. So yet again I modified the settings in /etc/systemd/logind.conf to prevent it from suspending and this time it worked, kind of. Now I am experiencing the screen going off and I have to change to a different tty (by using ctrl-alt-fx, which was something I also found I had to do sometimes when waking up from suspend in Ubuntu) to get the screen to go back on. The strange thing is this only happens when running a Linux distros and only occasionally (e.g. it may happen once/twice a week at most). But when it does happen it can happen multiple times in a row. And it only seems to happen when I am using it. This may just mean that it hasn't happened yet when I am not but generally if I leave it to run something or play a video it hasn't occurred only when I am using it regardless of which program I am using (e.g. it has occurred when using firefox, vim, even when using a virtualbox vm). At first I thought it could be the CPU temperature but after monitoring it I discovered it occurred a lot of the time when my CPU was less than 50 °C. I then checked /var/log/* but could not see anything related to it suspending only a few standard things from when it was woken up. I am really out of ideas and really hoping someone can help. Thanks in advance.
