General :: Process Gnome-appearance-properties Causing 100 Percent CPU Usage
Mar 18, 2011I 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.
View 3 Replies View RelatedDebian :: Gnash Causing 100% CPU Usage?
Mar 27, 2011I just installed Debian 6.0 on an older box, the CPU is an AMD K6-2 (with 3D Now) 500MHz, with 512Mb of on-board memory.
I installed this with the LXDE as the desktop environment and it includes a CPU usage graph (colored green) on the LXDE panel, by default. Based on my past experience with Linux, LXDE runs faster on this hardware than XFCE or Gnome.
When I use a web browser on this system, whether it is Iceweasel or Chromium, the CPU usage spikes up to 100%.
I believe Gnash may have something to do with this. I removed gnash which also removed browser-plugin-gnash and went to the same sites afterwards, the CPU usage then dropped considerably.
I realize that the CPU is somewhat slow (compared to today's processors), but why would Gnash (and probably by extension, Adobe Flash Player as well) use up all the CPU resources?
The installed video card is an nVIDIA GeForce 2 MX400 (PCI) with 32Mb of on-board video memory. I have another video card that could be used, a 3dfx Voodoo3 2000 PCI with 16Mb of on-board video memory. which I believe is also supported by xorg. The monitor is a Sceptre X9G-Naga III LCD, 19", resolution is 1024x768 (the maximum listed in the settings).

Apr 24, 2010When I reboot my computer I cannot see my Tuner card until I manually restart the MythTV backend.
the problem is that the backend is being started before the drivers to the tuner card (HVR-2250). is there a way to change this.
I figure I should ask here as more people know there way around start up commands. I figure the easiest thing to do is to edit this file:
Code:
/etc/init/mythtv-backend.conf
I would think adding a sleep or wait command would do the trick?

Ubuntu :: Memory Leaking Process Causing Hang After Login / Sort It?
Jun 10, 2011I'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?

Jul 15, 2011I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns.
However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?

General :: Way To Limit CPU Usage For Some Process?
Sep 21, 2009I'm writing a shell script which aims to create a safe gtared (xxx.sql.gz) copy of MySQL databases.This script is planned to be Cron-Jobed.
Well, what I need to add to this shell, is something that limit CPU usage for the whole process (just in case if the database being generating is a huge one.)So, after few time of googling I found couple of solutions:
- Using cpulimit.
I tried to place the code in Position(1) and Position(2) but it didn't seem to be working fine.. Any idea about the right use?
And the other Solution is:- Using nice.
Well, assuming I named my shell script (sqlbacker)..
Finally, this is my first time I ever write a shell, so correct me if somewhere I made a mistake :-)
(The script itself works perfectly)

General :: Need To Limit CPU Usage Of Process
Jan 26, 2010There's a disfunctional process eating copious cpu time.Is there a way to effectively assign it a high nice value? I need to do this whenever it runs, for whatever reason, and I can't be bothered to track down all the scripts and scenarios that cause it to run and change the script to use nice. And I can't be bothered to manually run renice whenever I notice that it's running.
I want the OS to automatically assign a high nice value to this process, perhaps based on the processes name. Is this possible?Presumably, a cron job could run every 5 minutes and run "renice" on every process matching a given name, but I'm hoping for a solution with more finess.

View 3 Replies View RelatedGeneral :: Big Cpu Usage But Top Shows No Heavy Use Process
May 6, 2011I have been running to a strange problem. For a few days, a few times a day something seems to take over my machine. Suddenly I can't type, or the key shows up about 5 seconds are being pressed, music players halt, etc. In anticipation, I had top and htop running. Sure enough, when this business begins htop reports all 8 cores firing at near 100% for a few minutes. However, top is telling me nothing about who is too blame. The cup%sy on top shows heavy usage, but the top processes are nothing remarkable, mostly just top and htop and conky, all running at around 1 or 2% on average. I am a bit puzzled as to why I can't see the cpu hog so that I figure out what is going on. My question then: Are there some processes (in kernel space?) that don't show up in top, yet which could be hogging the cpu?

General :: Calculating Process Memory Usage?
May 13, 2010What originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.
When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.
Code:
CALC=0
for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
pr -TW$COLUMNS |
grep main_server |
grep -v "grep main_server" |
[Code]...
Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.

Mar 13, 2010We have an internal application which takes below 10% cpu usage normally. However sometimes it hit above 85% or more (and stays there) causing the server to become very slow. Currently we have to monitor this manually, kill the process and manually start it.
command / script that will kill the process (using pid will be the best option as i think) when it reaches 85% or higher
(I saw another question that suggested to use monit but I have to get this done using the standard commands available in the current installation - RHEL5)

Jan 26, 2011I am using qmail in my office. I am noticing this for more than a month. It is my daily routine to check the cpu utilization using top command and by using top different processes can be viewed. the apache process after 1 or 2 days shows cpu utilization of 100%. There is no affect on the server whatsoever of 100% because mail server has 2 processors of 4 core, i think so that may be the reason. Can any one explain why is this happening. What i do after that is i restart the httpd process and cpu utilization comes to normal. What are the reasons behind this and how to solve this permanently.
