Ubuntu :: Memory Leaking Process Causing Hang After Login / Sort It?
Jun 10, 2011
I'm still pretty new to the linux scene but kubuntu has been a great alternative to ubuntu (unity, ugh) until now.
It only started happening since i started messing around with play on linux but i dont think their related. I dont think its a driver issue either as ive switched between proprietary and default to no avail.
Basically after i log in, it takes over 3-6 minutes getting slower and slower before finally getting back to regular speed. So after a few occurences i decided that immediately after startup i went to system monitor and sure enough;
There is a process title "akonadi_contact" that is slowly growing in memory. There are also multiple occurences of it (usually between 6 and 9). they keep growing usually to the 500000k mark in memory usage before turning gray (swap storage??) and then eventualy the end.
What is "akonadi_contact"
How do i stop this from happening.
Is this a memory leak?
I have been looking for a lightweight bandwidth monitoring app and came across bmon. It does what I need. However it has an interesting way of exiting.
when it is running and you close it down it ask you 'Really quit (y/n)' and does not shut down. I am used to just right clicking on my desktop and selecting 'leave' when it comes to shutdown time.
A few times now the laptop hangs on shutdown if bmon is open. I guess it is due to the app asking if it should shutdown. Is there a way to disable the app asking or alternatively nuke it for sure with some script on shutdown.
I could search the relevant konsole running the app and go thru the steps to shut it down but sometimes I am in a hurry and it doesn't feel like the way to go anyhow?
I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.
I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.
All connections on my computer start loading and then hang: it happens when running apt-get update (a few repositories load successfully and then it hangs at a random one) and when loading web pages with the browser (it says "Connecting...", then "Waiting for....", sometimes some part of the page loads, and then it hangs).
This happens both with my wired and my wireless connection. It does not happen on Windows on the same computer.
Whenever someone copies a data Our system get very slow. Load average of system starts increasing. How would i find which process is causing the same. I have tried following top 10 CPU utilizing process command but it didn't help much.
Code:
ps -auxf | sort -nr -k 3 | head -10
My distribution detail.
Code:
# lsb_release -a LSB Version: :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch Distributor ID: EnterpriseEnterpriseServer
I am using Rhythmbox 0.12.8 on Lucid 64-bit. In the "Your Downloads" window, it shows many of the tracks with "0MB downloaded" and one with "Queued", and doesn't really seem to be showing any progress.
addition 1: I completely shutdown RB, opened Ubuntu One from the MY Menu and placed a check mark in the "file synchronization" box. It seems to be working now. I had forgotten I turned off the file synchronization.
After updating to kernel-2.6.33.6-147.fc13.x86_64 (and updating all kmods) VirtualBox guests no longer boot.
I had a Windows guest (from now on refereed as Crapdows) that worked normally. After the update, I could get to the "Start Windows Normally" screen, but then Crapdows refused to boot. At first, I thought it was a crappy M$ bug, but after creating another VM (Doublecrap), and starting from scratch, I was able to get to the "Windows is loading files" screen, and then the guest hangs again. This problem is generalized to all OS'es I've tried. In Ubuntu, I can get to the language selection screen before the installation freezes. The same applies for Fedora and SUSE guests.
I am running a HP dc5750 dual core computer with a 512MB Nvidia 7200/7300 graphics card my operating system is Ubuntu 10.10. Both my processors are operating at 98-104% cpu usage, it appears that gnome-appearance-properties is the culprit and the only way to return to normal is to end these processes. I have been setting up the desktop cube to my liking and the processor appears to rise up to 100% again. Would getting a 1GB graphics card correct this or is this a bug in maverick meerkat. Any advice would be appreciated. Please keep it simply as I am a Newbie to Linux and find things over-whelming at times. Also would running at 100% on both processors at indefinite periods of time harm my computer.
For Linux command sort, how do I force sort to load all input into memory and sort assuming I have enough memory? Or is it best to use a RAMDISK to store the input before feeding it to sort?
When I install the ATI graphics driver, sure - I get all the screen resolutions I could possibly want, but the cost appears to be that it makes it causes my system to freeze at the user name and password screen. Sometimes the cursor blinks teasingly, but nothing appears as I type; sometimes the cursor itself is frozen.
My question isn't about the myriad of theoretical key combinations that might work - none of them have thus far.
I'm wondering whether I can simply continue using the default driver that the debian installer (ver. 8 stable 'Jessie') installed on my system. It's true that I only get 3 choices of screen resolution - 1152x864, 1024x768, and 800x600 - but my system seems so much more stable than when I install the proprietary ATI driver.
Aside from the login screen freezing - more often than not, strange things were happening keyboard wise - especially when composing posts for forums - the cursor would suddenly jump to another line of previously composed text for example!
So, can I keep the default driver or is it best to install the ATI driver and attempt to troubleshoot it? Is it even possible to troubleshoot a problematic driver - I knew how to do such things in Windows, but still learning about linux.
Also, when my system freezes at login (for whatever reason), if I'm obliged to simply hit the laptop power button to power down and press it again to restart - is this potentially damaging/corrupting my system - Debian, or indeed my hard drive?
Going forward, is the ATI driver issue likely be addressed in future Debian releases? Obviously, I would prefer to have the proper driver installed so as to have more screen resolution options - since I will be using my laptop for developing and testing web sites.
I understand that in linux virtual memory would be the same as swap and I also understand that linux only uses swap when your computer has used all your pc memory. I hope both assumption are right.Can I make a process like firefox use ONLY virtual memory/swap? No access to RAM.
I have a very old 386 AMD computer that stopped working. it woun't boot. I have noticed that the CMOS battery is leaking there is turquoise residue on the corner of the motherboard. Some of the copper traces seem darkened, I can't seem to see if the acid have etched through the copper traces. Does anybody know how to fix this, will a new battery fix it or is the turquoise residue able to etch through the copper traces? The battery is not the standard one. Its the green one on the picture: [URL]
I installed a fresh copy of Slackware 13.1 (stable) on one of my media servers and I am experiencing something strange.... When I power up the machine, I see the kernel booting, no errors, until it gets to the point where it says:
And then randomly freeze there.... Well the machine is not totally frozen because the cursor still blinks. But it will never continue... Like I said, this happens on a random basis... After a reset, it might go through or simply stall at the same spot.
I remember after installing Slack 13.1, I rebooted the machine but forgot to remove the DVD from the player, so the install routine started up, and froze at the same point when it was loading the kernel for the setup programs...
My mobo is a MSI k9N platinum.
I never had this problem before.... (well I never used 13.1 before). Since I got this machine, I used slack 12.2 and slack 13-current with success.
This problem makes the machine extremely unreliable because I intent to use it as a backup and media server, so chances I will WOL the machine and use it remotely... if that happens.
I have been assigned a school project on detecting memory leaks in linux processes. I am reading.. but have found it hard and inefficient to go through the very vast documentation not knowing what to really look for. Could you please give me some guidelines on this subject?
Is there any command to get the memory utilization of a particular process in Linux?I tried with Top and /proc/pid/status commands but the results are not proper, the memory keeps on increasing.Can anyone tell other than Top and /proc/pid/status commands ?
I need to know, what process for what purpose is using memory in my machine. ps utility with various options seems to give not exactly what i want, i.e. if i sum all the values like RSS, VSZ or some other values related to memory usage, the sum is not equal (even approximately) to what i get using free|grep "buffers/cache". How can i get this information? Even better, i would like to see contribution of every process, ramdisk, etc. to memory usage.
Need explanation about low level (like assembly level) memory management? Such as, how does a process acquire more memory, sharing memory among processes, etc. I don't want to know how to use malloc or other library functions, but more along the lines of how an example malloc implementation would acquire memory.
I used 9.04 for months and it work fine before restarting my PC. After I restarted my PC, the memory consumption takes up to 4.2 GB after login. However, I cannot find any process that consume such large number of memory.
In linux, how can I display memory usage of each process if i do a 'ps -ef'?I would like to the 'virtual memory', 'res memory', 'shared memory' of each progress. I can get that via 'top', but I want the same info in 'ps -ef ' so that I can pipe the output to 'grep {my process name}'.
I am running a series of tests for an implementation of a remote pager that sends page faults to other computers in a network. Long story short, I was wondering if there is an easy way to force a process to use virtual memory as oppose to physical RAM so that I can better measure the performance of my implementation against how the system would perform while swapping to the hard drive.
Im using SUSE, i have 31GB of memory Mem: 31908592k total, 31429632k used, 478960k free, 12176k buffers. How do I find out what process are eating up all my memory.
Does anyone know of a linux utility which will prevent all memory in a forked process from being swapped out to disk? I've seen the 'mlockall' call, but hacking the app sounds like overkill.My reason for needing this is that I'm running Windows XP under VirtualBox on my linux netbook, and I'm concerned there are basically two levels of swapping going on, which on a single dinky netbook hard disk isn't
