I was getting seg faults as well but using the latest svn version fixed this for me:

svn checkout https://cpulimit.svn.sourceforge.net/svnroot/cpulimit/trunk cpulimit
make
cp cpulimit /usr/local/sbin

yum install subversion if necessary.

Thank you very much. Saved my butt on a broken Acer Aspire 5715Z that has an abysmall overheating problem constantly triggered by Firefox. Amazingly, I haven’t even noticed any performance decrease at 30%. CPU temperature dropped to 68 degrees celcius, from unoperatable 98 degrees. Beautiful.

Why cpulimit_daemon.sh script does not work in CentOS 5.5 (kernel 2.6.18)?
And if you run:
cpulimit-P / opt / firefox / firebox-l 30
then cpulimit works fine.

Hi, I am fairly new to Linux. I followed your instructions and was able to install cpulimit – Thanks! My question is: I have a scheduled backup job that starts/stops a “java” process which hammers the CPU. Is there a way to auto-limit the the CPU usage of the java process when it starts?

@ Pugazendhi,

Thanks for the heads up, it was a typo on my part!

tar cpulimit-1.1.tar.gz
returned, on CentOS, “/bin/tar: Old option `g’ requires an argument.”
The following worked.
tar -xvzf cpulimit-1.1.tar.gz

@Josh

Run this “cpulimit -l -e gzip”. Leave it running, for example, in a detached screen or in background adding the character “&” at the end.

I am trying to limit the gzip process, however, it isn’t currently running. Is there a way to make it so whenever a process runs it is limited?

@Slawek

At current version of cpulimit (1.1) does *not* support programs execution directly from cpulimit.
You have two ways to do it:
- First, limit the cpu usage of gzip command and then, run gzip.
- Run gzip and then limit its cpu usage with cpulimit.

Only development version support programs execution directly.

Sorry original command was:
gzip -1 file.gz
# cpulimit -l 30 -e gzip -1 file.gz
cpulimit: invalid option — ’1′

I would like to limit CPU usage by command :
gzip -9 somename.gz
How to use cpulimit with it.
# cpulimit -l 30 -e gzip -1 file.gz
cpulimit: invalid option — ’1′
Any ideas ?
regards to you all

Thanks, but i get an error:

Segmentation fault (core dumped)

An core dump file is created when i run cpulimit for limit apache (httpd).

My server is an Core2Quad 64 Bits…maybe cause i’m using 64 Bits?

Thanks!
