  • Apache strace to hunt down a memory leak

    - by Zipp
    We have a server with a memory issue: the server keeps allocating itself memory and doesn't release it. We're running Apache. I set MaxReqsPerClient to a really low value just so the threads don't hold a lot of memory, but has anyone seen calls like this? Am I wrong in thinking that it's probably Drupal pulling too much data back from the cache in DB? read(52, "h_index\";a:2:{s:6:\"weight\";i:1;s"..., 6171) = 1368 read(52, "\";a:2:{s:6:\"author\";a:3:{s:5:\"la"..., 4803) = 1368 read(52, ":\"description\";s:19:\"Term name t"..., 3435) = 1368 read(52, "abel\";s:4:\"Name\";s:11:\"descripti"..., 2067) = 1368 read(52, "ions\";a:2:{s:4:\"form\";a:3:{s:4:\""..., 16384) = 708 brk(0x2ab554396000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f653000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f753000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f853000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55f953000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fa53000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fb53000 brk(0x2ab554356000) = 0x2ab5542f5000 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2ab55fc53000 poll([{fd=52, events=POLLIN|POLLPRI}], 1, 0) = 0 (Timeout) write(52, "d\0\0\0\3SELECT cid, data, created, "..., 104) = 104 read(52, "\1\0\0\1\5E\0\0\2\3def\23drupal_database_nam"..., 16384) = 1368 read(52, ";s:11:\"granularity\";a:5:{s:4:\"ye"..., 34783) = 1368 read(52, ":4:\"date\";}s:9:\"datestamp\";a:9:{"..., 33415) = 1368 read(52, "\";i:0;s:15:\"display_default\";i:0"..., 32047) = 1368 read(52, "e as an integer value.\";s:8:\"set"..., 30679) = 1368 read(52, "label' pairs, i.e. 'Fraction': 0"..., 29311) = 1368 top (the procs just keep growing in memory..): 12845 apache 15 0 581m 246m 37m S 0.0 4.1 0:17.39 httpd 12846 apache 15 0 571m 235m 37m S 0.0 4.0 0:12.13 httpd 12833 apache 15 0 420m 117m 37m S 0.0 2.0 0:06.04 httpd 12851 apache 15 0 412m 113m 37m S 0.0 1.9 0:05.32 httpd 13871 apache 15 0 409m 109m 37m S 0.0 1.8 0:04.90 httpd 12844 apache 15 0 407m 108m 37m S 0.0 1.8 0:04.50 httpd 13870 apache 15 0 407m 108m 37m S 0.3 1.8 0:03.50 httpd 14903 apache 15 0 402m 103m 37m S 0.3 1.7 0:01.29 httpd 14850 apache 15 0 397m 100m 37m S 0.0 1.7 0:02.08 httpd 14907 apache 15 0 390m 93m 36m S 0.0 1.6 0:01.32 httpd 13872 apache 15 0 386m 91m 37m S 0.0 1.5 0:03.13 httpd 12843 apache 15 0 373m 81m 37m S 0.0 1.4 0:02.51 httpd 14901 apache 15 0 370m 75m 33m S 0.0 1.3 0:00.78 httpd 14904 apache 15 0 335m 29m 15m S 0.0 0.5 0:00.26 httpd

  • crunchbang: it takes up *how* much memory?!?!

    - by Theo Moore
    I've been trying many distros of Linux lately, trying to find something I like for my netbook. I started out with Ubuntu, and I can tell you I am a big fan. Ubuntu is now fast to install, much simpler to administer, and pretty light resource-wise. My original install was the standard 32 bit version of 9.04. I tried the netbook remix version of this release, but it was very, very slow. Even the full-blown version used only about 200mb. Much better than the almost 800 that the recommended Windows y version took. Once the newest release of Ubuntu was released, I decided to try the netbook remx of 10.04. It used even less RAM; only about 150mb. I thought I'd found my OS. I certainly settled in and prepared to use it forever. Then, someone I know suggested I try cunchbang. It is the most minimalistic UI I've ever seen, using Openbox rather than Gnome or KDE. Very slick, simple and clean. Since I am using the alpha of the most recent version (using Debian Squeeze), the apps provided for you are few...although more will be provided soon. You do have a word processor, etc., although not the OpenOffice you would normally get in Ubuntu. But the best part? 48MB. That's it. 48mb fully loaded, supporting what I can "hotel services". It's fast, boots quick, and believe it or not, I can even do Java-based development....on my netbook! Pretty slick.   More on it as I use it.

  • PHP-FPM Pool, Child Processes and Memory Consumption

    - by Jhilke Dai
    In my PHP-FPM configuration I have 3 Pools, the eg: Config is: ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 1 ; ;;;;;;;;;;;;;;;;;;;;;;; [www1] user = www group = www listen = /tmp/php-fpm1.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 2 ; ;;;;;;;;;;;;;;;;;;;;;;; [www2] user = www group = www listen = /tmp/php-fpm2.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 ;;;;;;;;;;;;;;;;;;;;;;; ; Pool 3 ; ;;;;;;;;;;;;;;;;;;;;;;; [www3] user = www group = www listen = /tmp/php-fpm3.sock; listen.backlog = -1 listen.owner = www listen.group = www listen.mode = 0666 pm = dynamic pm.max_children = 40 pm.start_servers = 6 pm.min_spare_servers = 6 pm.max_spare_servers = 12 pm.max_requests = 250 slowlog = /var/log/php/$pool.log.slow request_slowlog_timeout = 5s request_terminate_timeout = 120s rlimit_files = 131072 I calculated the pm.max_children processes according to some example calculations on the web like 40 x 40 Mb = 1600 Mb. I have separated 4 GB of RAM for PHP, now according to the calculations 40 Child Processes via one socket, and I have total of 3 sockets in my Nginx and FPM configuration. My doubt is about the amount of memory consumption by those child processes. I tried to create high load in the server via httperf hog and siege but I could not calculate the accurate memory usage by all the PHP processes (other processes like MySQL and Nginx were also running). And all the sockets were in use, So, I seek guidance from anyone who have done this before or know how exactly the pm.max_children in PHP Works. Since I have 3 Pools/sockets with 40 child processes does that count to 3 x 40 x 40 Mb of Memory usage ? or it is just like 40 Max. Child processes sharing 3 sockets (and the total memory usage is just 40 x 40 Mb) ?

  • Why, in WPF, do we set an object to Stretch via its Alignment properties instead of Width/Height?

    - by Jonathan Hobbs
    In WPF's XAML, we can tell an element to fill its container like this: <Button HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> Why is it that when we set an element to Stretch, we do it via the HorizontalAlignment and VerticalAlignment properties? Why did the WPF design team decide to take this approach over having Width="Stretch" and Height="Stretch"? I presume it was a calculated decision, and I'm curious about the reasoning. CSS, among other technologies, follows the convention that stretching is done via the width and height properties, and that alignment affects positioning exclusively. This seems intuitive enough: stretching the element is manipulating its width and height, after all! Using the corresponding alignment property to stretch an element seems counter-intuitive and unusual in comparison. This makes me think they didn't just pick this option for no reason: they made a calculated decision and had reasons behind it. Width and Height use the double data type, which would ordinarily mean assigning it a string would be silly. However, WPF's Window objects can take Width="Auto", which gets treated as double.NaN. Couldn't Width="Stretch" be stored as double.PositiveInfinity or some other value?

  • XNA Shader Texture Memory

    - by Alex
    I was wondering about texture optimization in XNA 4.0. Will the the contentmanager send the texturedata to the GPU directly when the texture gets loaded or do I send the texture data to the GPU when I declare a texture in my shader. If that's the case, what happens if I have 5 shaders all using the same texture, does that mean that I send 5 instances of that texture data to the gpu or am I simply telling the GPU what preloaded texture to use? Or does XNA do the heavy lifting in the background?

  • Why Hekaton In-Memory OLTP Truly is Revolutionary

    - by merrillaldrich
    I just returned from the PASS Summit in Charlotte, NC – which was excellent, among the best I have attended – and I have had Dr. David DeWitt’s talk rolling around in my head since he gave it on Thursday. (Dr. DeWitt starts at 27:00 at that link.) I probably cannot do it justice, but I wanted to recap why Hekaton really is revolutionary, and not just a marketing buzzword. I am normally skeptical of product announcements, and I find too often that real technical innovation can be overwhelmed by the...(read more)

  • Learning about BIOS memory, instructions and code origins

    - by m3taspl0it
    I'm learning about the BIOS and have a few questions. What is meant by, "This is the last 16 bytes of memory at the end of the first megabyte of memory"? The first instruction of BIOS is jump, which jumps to the main BIOS program, but where does it jump? Where does the original BIOS code originate? I'm also interested in POST? How are POST signals executed by the processor?

  • Copy to USB memory stick really slow?

    - by Eloff
    When I copy files to the USB device, it takes much longer than in windows (same usb device, same port) it's faster than USB 1.0 speeds (1MB/s) but much slower than USB 2.0 speeds (12MB/s). To copy 1.8GB takes me over 10 minutes (it should be < 3 min.) I have two identical SanDisk Cruzer 8GB sticks, and I have the same problem with both. I have a super talent 32GB USB SSD in the neighboring port and it works at expected speeds. The problem I seem to see in the GUI is that the progress bar goes to 90% almost instantly, completes to 100% a little slower and then hangs there for 10 minutes. Interrupting the copy at this point seems to result in corruption at the tail end of the file. If I wait for it to complete the copy is successful. Any ideas? dmesg output below: [64059.432309] usb 2-1.2: new high-speed USB device number 5 using ehci_hcd [64059.526419] scsi8 : usb-storage 2-1.2:1.0 [64060.529071] scsi 8:0:0:0: Direct-Access SanDisk Cruzer 1.14 PQ: 0 ANSI: 2 [64060.530834] sd 8:0:0:0: Attached scsi generic sg4 type 0 [64060.531925] sd 8:0:0:0: [sdd] 15633408 512-byte logical blocks: (8.00 GB/7.45 GiB) [64060.533419] sd 8:0:0:0: [sdd] Write Protect is off [64060.533428] sd 8:0:0:0: [sdd] Mode Sense: 03 00 00 00 [64060.534319] sd 8:0:0:0: [sdd] No Caching mode page present [64060.534327] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.537988] sd 8:0:0:0: [sdd] No Caching mode page present [64060.537995] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.541290] sdd: sdd1 [64060.544617] sd 8:0:0:0: [sdd] No Caching mode page present [64060.544619] sd 8:0:0:0: [sdd] Assuming drive cache: write through [64060.544621] sd 8:0:0:0: [sdd] Attached SCSI removable disk

  • Memory allocation strategy for the vertex buffers (DirectX 10/11)

    - by Alex
    I have the following question. I write CAD system. So I have a 3D scene and there are many different objects (walls, doors, windows and so on). User can add or delete some objects. The question is: how can I organise the keeping of vertices for all my objects. I can create vertex buffer for every object. But I think drawing/switching from one buffer to another would have performance penalty. Another way - I can create several big buffers for every object type. But I don't understand how to update such buffers. It is too big to update whole buffer (for example buffer for all walls). What I need to do if I want to delete the object from the middle of the buffer? Actually I have the similar question: http://stackoverflow.com/questions/5515700/how-to-properly-update-vertex-buffers-in-directx-10 Most examples I've found work with very static models. Therefore, they tend to create a single vertex buffer with their list of points, and then are just manipulated by matrix transformations. I, on the other hand, will be updating the scene very often.

  • How to tune system settings for mongoDB on Linux?

    - by jsh
    Trying to squeeze a lot out of one question here -- please bear with me. Although the MongoDB man pages make several useful recommendations about system settings like ulimit (http://docs.mongodb.org/manual/reference/ulimit/), and other production factors (http://docs.mongodb.org/manual/administration/production-notes/) they seem mysteriously silent on things like virtual memory and swap settings. The closest we get to a hint is that "...the operating system’s virtual memory subsystem manages MongoDB’s memory..." (http://docs.mongodb.org/manual/faq/fundamentals/#does-mongodb-require-a-lot-of-ram). Running the same job - high writes and high reads on about 10,000,000 records in a single collection -- on my 4-processor, 4GB RAM macbook and an 8-core ubuntu box with 64GB RAM I saw dramatically WORSE read performance on the linux box with factory settings, and could hear the disk constantly spinning, indicating high I/O and presumably swapping. Yes, other things were happening on the box, but there was plenty of free RAM, disk space, etc.; furthermore, I did not see evidence that Mongo was expanding to take advantage of all that free RAM as it is touted to do. Linux box default settings were as follows: vm.swappiness =60 vm.dirty_background_ratio = 10 vm.dirty_ratio = 20 vm.dirty_expire_centisecs =3000 vm.dirty_writeback_centisecs=500 I hazarded some guesses looking at docs and blogs for other types of databases (Oracle, MYSQL, etc.), experimented, and adjusted as below. vm.swappiness=10 vm.dirty_background_ratio=5 vm.dirty_ratio=5 vm.dirty_writeback_centisecs=250 vm.dirty_expire_centisecs=500 I saw some immediate apparent improvements in read time. However, when I ran my test jobs again, read performance continued to be painfully sluggish during heavy writes. Then, I REBUILT the collection from an available data source - and suddenly I can read at 1ms or less per record WHILE doing the write job! So the question is really two-fold: 1) What are appropriate VM settings for MongoDB on Linux? 2) (bonus) Does Mongo do some checking or optimization with the OS while data is being built? In other words, if I have built a large data set with suboptimal VM or I/O settings, does Mongo make assumptions during the memory-mapping process that will fail to take advantage of optimizations down the road? Obviously I don't fully grok memory mapping under the hood (I was hoping I wouldn't have to). Any help appreciated...thanks! -j

  • NK2 files doesn't keep the email addresses in memory

    - by r0ca
    When I send an email to someone outside the firm, when I only type the first letters of its name (Contact), I get the auto-suggest of the "Already-sent" users. So now, since a few days, the emails are not kept in memory by Outlook (NK2 file). I see that that file is only 2kb and on my old machine, it's almost 200kb (So a lot more email addresses kept in memory) Should I just rebuilt the Outlook profile or the whole Windows Profile? A simple Outlook reinstall or to build a new PC?

  • Fail2ban memory usage

    - by ltsstar
    Since my server is under a sustain DNS amplification attack (DDOS), I configured fail2ban and initially my outgoing traffic dropped markedly. Anyway, after a few hours (mostly +10), fail2ban uses about 75% ram and seems to be crashed in some way, because the outgoing traffic raises imediatly after. When I searched the web for the memory problem, I found some people complaining about high fail2ban memory usages as well. But the recommended solution, to insert an ulimit command into a fail2ban config file, did not change that much for me.

  • Enabling Squid delay pool eats up the entire memory

    - by Supratik
    I am using "squid-3.1.8-1.el5" in my CentOS 5 32 bit system. In normal condition Squid uses 85m - 90m, but when I enable the delay pool parameters the memory usage suddenly rise up 2GB. The memory keeps on increasing until the system is out of resource. The following are my delay pool settings: delay_pools 1 delay_class 1 1 delay_access 1 allow all delay_parameters 1 192000/192000 Is there anything I am missing here or is it a bug with Squid ?
