• How to move packages from the live image to a pool on the disc?

  - by int_ua

  Currently I'm using UCK and trying to make Edubuntu 12.04.1 DVD launch installer on 256Mb RAM: How to install Edubuntu on a system with low memory (256 Mb)? I was reading release notes for 12.10 and noticed that Language packs have now been moved off from the live image to a pool on the disc. How can I move other packages correctly so they would be available to the live system and for installation without network access?

• Two bugs you should be aware of

  - by AaronBertrand

  In the past 24 hours I have come across two bugs that can be quite problematic in certain environments. LPIM issue with SetFileIoOverlappedRange Last night the CSS team posted a blog entry detailing a potential issue with Lock Pages in Memory and Windows' SetFileIoOverlappedRange API. I tweeted about it at the time, but thought it could use a little more treatment. The potential symptoms can vary, but include the following (as quoted from the blog post): Wide ranging in SQL from invalid write location,...(read more)

• iPhone app memory leak with UIImage animation? Problem testing on device

  - by user157733

  I have an animation which works fine in the simulator but crashes on the device. I am getting the following error... Program received signal: “0”. The Debugger has exited due to signal 10 (SIGBUS) A bit of investigating suggests that the UIImages are not getting released and I have a memory leak. I am new to this so can someone tell me if this is the likely cause? If you could also tell me how to solve it then that would be amazing. The images are 480px x 480px and about 25kb each. My code is below... NSArray *rainImages = [NSArray arrayWithObjects: [UIImage imageNamed:@"rain-loop0001.png"], [UIImage imageNamed:@"rain-loop0002.png"], [UIImage imageNamed:@"rain-loop0003.png"], [UIImage imageNamed:@"rain-loop0004.png"], [UIImage imageNamed:@"rain-loop0005.png"], [UIImage imageNamed:@"rain-loop0006.png"], //more looping images [UIImage imageNamed:@"rain-loop0045.png"], [UIImage imageNamed:@"rain-loop0046.png"], [UIImage imageNamed:@"rain-loop0047.png"], [UIImage imageNamed:@"rain-loop0048.png"], [UIImage imageNamed:@"rain-loop0049.png"], [UIImage imageNamed:@"rain-loop0050.png"], nil]; rainImage.animationImages = rainImages; rainImage.animationDuration = 4.15/2; rainImage.animationRepeatCount = 0; [rainImage startAnimating]; [rainImage release]; Thanks

• Memory Leaks when touching UITableViewCells and poping off view.

  - by Falcon

  Hi All, I'm currently having a problem where the leaks tool is reporting a slew of memory leaks after clicking on cells within a UITableView and then hitting the back button and popping off the view. Majority of the leaks reported can not be traced back to any specific location in my code, they are: Leaked Object # Address Size Responsible Library Responsible Frame NSCFArray 2 < multiple > 64 UIKit -[UITouch(UITouchInternal) UITouch 2 < multiple > 128 GraphicsServices PurpleEventCallback Malloc 48 Bytes 2 < multiple > 96 Foundation -[NSCFArray insertObject:atIndex:] UIDelayedAction 2 < multiple > 96 UIKit -[UILongPressGestureRecognizer startTimer] NSCFArray 2 < multiple > 64 UIKit -[UILongPressGestureRecognizer touchesBegan:withEvent:] Malloc 32 Bytes 2 < multiple > 64 Foundation -[NSCFArray insertObject:atIndex:] Malloc 16 Bytes 2 < multiple > 32 Foundation -[NSCFSet unionSet:] Now I have commented out all my code in any touch event functions that I have written and it still leaks if I click on the cell a few times and then hit the back button to return to the previous view. Any ideas on what might actually be the problem here? Thanks,

• Python: Does one of these examples waste more memory?

  - by orokusaki

  In a Django view function which uses manual transaction committing, I have: context = RequestContext(request, data) transaction.commit() return render_to_response('basic.html', data, context) # Returns a Django ``HttpResponse`` object which is similar to a dictionary. I think it is a better idea to do this: context = RequestContext(request, data) response = render_to_response('basic.html', data, context) transaction.commit() return response If the page isn't rendered correctly in the second version, the transaction is rolled back. This seems like the logical way of doing it albeit there won't likely be many exceptions at that point in the function when the application is in production. But... I fear that this might cost more and this will be replete through a number of functions since the application is heavy with custom transaction handling, so now is the time to figure out. If the HttpResponse instance is in memory already (at the point of render_to_response()), then what does another reference cost? When the function ends, doesn't the reference (response variable) go away so that when Django is done converting the HttpResponse into a string for output Python can immediately garbage collect it? Is there any reason I would want to use the first version (other than "It's 1 less line of code.")?

• Does the pointer to free() have to point to beginning of the memory block, or can it point to the interior?

  - by Lambert

  The question is in the title... I searched but couldn't find anything. Edit: I don't really see any need to explain this, but because people think that what I'm saying makes no sense (and that I'm asking the wrong questions), here's the problem: Since people seem to be very interested in the "root" cause of all the problem rather than the actual question asked (since that apparently helps things get solved better, let's see if it does), here's the problem: I'm trying to make a D runtime library based on NTDLL.dll, so that I can use that library for subsystems other than the Win32 subsystem. So that forces me to only link with NTDLL.dll. Yes, I'm aware that the functions are "undocumented" and could change at any time (even though I'd bet a hundred dollars that wcstombs will still do the same exact thing 20 years from now, if it still exists). Yes, I know people (especially Microsoft) don't like developers linking to that library, and that I'll probably get criticized for the right here. And yes, those two points above mean that programs like chkdsk and defragmenters that run before the Win32 subsystem aren't even supposed to be created in the first place, because it's literally impossible to link with anything like kernel32.dll or msvcrt.dll and still have NT-native executables, so we developers should just pretend that those stages are meant to be forever out of our reaches. But no, I doubt that anyone here would like me to paste a few thousand lines of code and help me look through them and try to figure out why memory allocations that aren't failing are being rejected by the source code I'm modifying. So that's why I asked about a different problem than the "root" cause, even though that's supposedly known to be the best practice by the community. If things still don't make sense, feel free to post comments below! :)

• BufferedImage.getGraphics() resulting in memory leak, is there a fix?

  - by user359202

  Hi friends, I'm having problem with some framework API calling BufferedImage.getGraphics() method and thus causing memory leak. What this method does is that it always calls BufferedImage.createGraphics(). On a windows machine, createGraphics() is handled by Win32GraphicsEnvironment which keeps a listeners list inside its field displayChanger. When I call getGraphics on my BufferedImage someChart, someChart's SurfaceManager(which retains a reference to someChart) is added to the listeners map in Win32GraphicsEnvironment, preventing someChart to be garbage collected. Nothing afterwards removes someChart's SurfaceManager from the listeners map. In general, the summarized path stopping a BufferedImage from being garbage collected, once getGraphics is called, is as follows: GC Root - localGraphicsEnvironment(Win32GraphicsEnvironment) - displayChanger(SunDisplayChanger) - listeners(Map) - key(D3DChachingSurfaceManager) - bImg(BufferedImage) I could have changed the framework's code so that after every called to BufferedImage.getGraphics(), I keep a reference to the BufferedImage's SurfaceManager. Then, I get hold of localGraphicsEnvironment, cast it to Win32GraphicsEnvironment, then call removeDisplayChangedListener() using the reference to the BufferedImage's SurfaceManager. But I don't think this is a proper way to solve the problem. Could someone please help me with this issue? Thanks a lot!

• Is there a more memory efficient way to search through a Core Data database?

  - by Kristian K

  I need to see if an object that I have obtained from a CSV file with a unique identifier exists in my Core Data Database, and this is the code I deemed suitable for this task: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity; entity = [NSEntityDescription entityForName:@"ICD9" inManagedObjectContext:passedContext]; [fetchRequest setEntity:entity]; NSPredicate *pred = [NSPredicate predicateWithFormat:@"uniqueID like %@", uniqueIdentifier]; [fetchRequest setPredicate:pred]; NSError *err; NSArray* icd9s = [passedContext executeFetchRequest:fetchRequest error:&err]; [fetchRequest release]; if ([icd9s count] > 0) { for (int i = 0; i < [icd9s count]; i++) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init]; NSString *name = [[icd9s objectAtIndex:i] valueForKey:@"uniqueID"]; if ([name caseInsensitiveCompare:uniqueIdentifier] == NSOrderedSame && name != nil) { [pool release]; return [icd9s objectAtIndex:i]; } [pool release]; } } return nil; After more thorough testing it appears that this code is responsible for a huge amount of leaking in the app I'm writing (it crashes on a 3GS before making it 20 percent through the 1459 items). I feel like this isn't the most efficient way to do this, any suggestions for a more memory efficient way? Thanks in advance!

• why is my centos, nginx, php,mysql server using so much memory

  - by kb2tfa

  i'm not sure where the problem lies. I have: centos 6 mysql php php-fpm wordpress (1 site). this is a dedicated server i'm learning on. as soon as i ran the web url the memory slammed to 125% of a 512k server, i had to upgrade to 1gig, so i'm not sure where the problem lies. I thought by switching to nginx from apache i would have more memory free, but i'm still stuck with the problem. before launching the site with nginx and mysqld running the site was about 5% memory. I reanamed my "my-small.cnf" to my.cnf and put in my /etc folder where the original was, but that seems not to have done it. after looking at my TOP results, i'm starting to think it may be php-fpm eating my memory, but not sure. is php-fpm the preferend way or is there something better to use.

• JVM process resident set size "equals" max heap size, not current heap size

  After a few reading about jvm memory (here, here, here, others I forgot...), I am expecting the resident set size of my java process to be roughly equal to the current heap space capacity.

• MKMapView memory usage grows out of control with setRegion: calls

  - by Kurt

  Hi, I have a single MKMapView instance that I have programmatically added to a UIView. As part of the UI, the user can cycle through a list of addresses and the map view is updated to show the correct map for each address as the user goes through them. I create the map view once, and simply change what it displays with setRegion:animated:. The problem is that each time the map is changed to show a new address, the memory usage of my program increases by 200K-500K (as reported by Memory Monitor in Instruments). According to Object Allocations, it appears that a lot of 1.0K Mallocs are happening each time, and the Extended Detail pane for these 1.0K allocations shows that the Responsible Caller is convert_image_data and the Extended Detail pane shows that this is the result of [MKMapTileView drawLayer:inContext:]. So, seems likely to me that the memory usage is due to MKMapView not freeing memory it uses to redraw the map each time. In fact, when I don't display the map at all (by not even adding it as a subview of my main UIView) but still cycle through the addresses (which changes various UILabels and other displayed info) the memory usage for the app does NOT increase. If I add the map view but never update it with setRegion:, the memory also does NOT increase when changing to a new address. One more bit of info: if I go to a new address (and therefore ask the map to display the new address) the memory jumps as described above. However, if I go back to an address that was already displayed, the memory does not jump when the map redraws with the old address. Also, this happens on iPad (real device) with 3.2 and on iPhone (again, real device) with 3.1.2. Here's how I initialize the MKMapView (I only do this once): CGRect mapFrame; mapFrame.origin.y = 460; // yes, magic numbers. just for testing. mapFrame.origin.x = 0; mapFrame.size.height = 500; mapFrame.size.width = 768; mapView = [[MKMapView alloc] initWithFrame:mapFrame]; mapView.delegate = self; [self.view insertSubview:mapView atIndex:0]; And in response to the user selecting an address, I set the map like so: MKCoordinateRegion region; MKCoordinateSpan span; span.latitudeDelta=kStreetMapSpan; // 0.003 span.longitudeDelta=kStreetMapSpan; // 0.003 region.center = address.coords; // coords is CLLocationCoordinate2D region.span = span; mapView.region.span = span; [mapView setRegion:region animated:NO]; Any thoughts? I've scoured the net but haven't seen mention of this problem, and I've reached the limits of my Instruments knowledge. Thanks for any ideas.

• Override the bounce recipient address in exim4

  - by jerhinesmith

  I have a small app that allows a user to share an item by generating an email to a supplied email address. We set the "from" and "reply to" values to be the sender's address, so that when the email reaches the recipient, it appears to have come from the sender. This works wonderfully except when an email gets bounced. Currently, on bounces, exim attempts to redeliver the message periodically while simultaneously sending error emails back to the sender. I'd rather have those emails basically routed to an empty mailbox somewhere as there's nothing really that the sender can do about it. I found some documentation on bounced emails here: http://www.exim.org/exim-html-4.67/doc/html/spec_html/ch46.html and it claims that "Exim sends a message to the original sender, or to an alternative configured address.", but it doesn't say exactly how to configure an alternative address. Ideas?

• VMWare Network bug in multiple VMWare Workstation versions if using a hardcoded IP address

  - by onyxruby

  I'm having a very tricky problem with some of my VM sessions being unable to reach the Internet or even ping the gateway. I have just set up a new VM Workstation (7) on a W2K8 64bit server (I'll be converting to ESXI 4 once I can find a decent book on it, so for the meanwhile I use workstation). I have imported a number of VM's and setup some new ones on the server.In short the problem with some of the VM's being unable to reach the Internet is that they can't reach the gateway. I've looking at a number of things and can pretty safely rule out the following: Switch, Router, DHCP Server, DNS, Client IP configuration, Routes and typos. The problem is that some of the new clients cannot reach the gateway if their IP address is hardcoded, they can't even ping it by IP address. That rules out DNS and DHCP. Now, if I allow them to get their IP address by DHCP they can reach the gateway and Internet without issue. The interesting thing on this, is that this behavior occurs even if I leave the DNS information hardcoded under TCP/IP settings. It doesn't work unless the IP and gateway are handed out by DHCP even though the same information IP info is being used by the host. Fundamentally from the standpoint of the clients, they are trying to reach the exact same gateway using the exact same IP information regardless of whether they are hardcoded or assigned by DHCP. Here's an example of one client. IP Address 192.168.7.66 - Subnet Mask 255.255.255.0 - Gateway 192.168.7.254 - DNS1 192.168.7.44 - DNS2 192.168.7.254. The issue occurs across six different microsoft operating systems, Windows 7 and Windows 2008 variants all have the issue. My W2K3, XP, Vista and W98 clients all work without issue with hardcoded IP addresses. I have tried things like rearranging the DNS order, flushing DNS and so on. It's not a routing or switch issue as the clients can work just fine if they get their IP by DHCP. It's not a paramater issue as the exact same paramaters are handed out by DHCP as I plug in by hand. It's not a DNS issue as clients cant reach other clients even with IP addresses only. I have run a tracert to the gateway by IP address and it times out on the very first hop before failing on hop3 with destination host unreachable. If I get the IP address by DHCP the tracert finds the gateway (and Internet) without issue. I have read a few other posts online in forums talking about this problem randomly occuring over the years in other VM versions as well, so I suspect some kind of long standing bug. Does anyone have any ideas on this? Is it possibly a bug with Windows 7 and W2K clients under VM?

• the Memory problem about MySQL "SELECT *"

  - by Austin Huang

  Dear all: I'm new to MySQL, and I have a question about the memory. I have a 200mb table(MyISAM, 2,000,000 rows), and I try to load all of it to the memory. I use python(actually MySQLdb in python) with sql: SELECT * FROM table. However, from my linux "top" I saw this python process uses 50% of my memory(which is total 6GB) I'm curious about why it uses about 3GB memory only for a 200 mb table. Thanks in advance!

• Routing based on source address in Windows Server 2008 R2

  - by rocku

  Hi, I'm implementing a direct routing load balanced solution using Windows Server 2008 R2 as back-end server. I've configured a loopback interface with the external IP address. This works, I am receiving packets with the external IP address and respond to them appropriately. However our infrastructure requires that traffic which is being load-balanced should go through a different gateway then any other traffic originating from the server, ie. updates etc. So basicly I need to route packets based on source address (external IP) to another gateway. The built-in Windows 'route' command allows routing based on destination address only. I've tried setting a default gateway on the loopback interface and mangled with weak/strong host send/receive parameters on the interfaces, however this didn't work. Is there any way around this, possibly using third party tools?

• subdomain on another ip address

  - by pixeline

  hello, my main domain (domain.com) sits on a server with ip address 1. I need to have a subdomain (forum.domain.com) point to a server with ip address 2. Both servers are hosted at iWeb, so i have a cPanel interface to manage them, but i can't find the right way to do that. I tried a .htaccess redirection, which works, but the visible address in the browser changes too. Any help on how to do that would be appreciated. Thank you

• ipv6 port 445 does not accept the request from a global type address

  - by blacktea

  I want to scan the port 445 in windows server 2003, but my scanner only have one type ipv6 address which is global not link-local. When I do this,I find that I can't find port 445 open. But I use the command "netstat -an" to assure the port 445 is listening. Finally I find this confusing phenomenon: 1.when I set a link-local ddress in my scanner, then it will work in scanning port 445. 2.when I only set a global address in my scanner, it doed not work. This means if a host with a link-local address use socket to send a syn packet to the port 445 in server 2003, it will receive a ack packet. But if with a global address it will receive a rst packet. Thus, I can't scan the port 445 in server 2003 with a global address. I need to know why? Can anybody help? And I use the netsh-firewall to check the exception and netsh-interface-ipv6 to turn off the firewall on the specific interface. Still can't establish the connection with port 445, do you have any ideal about this ?

• Assign fixed IP address via DHCP by DNS lookup

  - by Janoszen

  Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

• Why might PC3200 ECC ram be incompatible when upgrading?

  - by Zak

  I had some 512MB PC3200 Kingston mem modules in a server, and I ordered replacement Kingston memory in 1GB sticks. The vendor said they were out of stock and I agreed to let them ship me "compatible" Samsung memory. However, after installing, the MB posted BIOS errors and wouldn't even boot to a BIOS screen. Both memory was ECC PC3200. Any ideas why that would happen?

• Is it possible to rent an IP address to mask the server real IP address?

  - by net-girl

  A customer would like to lease an IP address and point it to a dedicated web server with the intention of "masking" the server's IP address so it would be difficult to tell where the site is hosted. I found a company that leases IP addresses here: http://www.webhostingtalk.com/showthread.php?t=1191688 Is this even possible? Can they rent an IP address from a 3rd party in order to hide the server's IP address? Update: My client will be hosting a government leaks site and is trying to become Raid-Proof similar to what the pirate bay did: http://torrentfreak.com/pirate-bay-moves-to-the-cloud-becomes-raid-proof-121017/ Only that I'm worried about using a reverse proxy because of the latency it could cause having the app servers hosted in one data center and the load balancer/reverse proxy in other and also having to pay twice for bandwidth.
