100% CPU usage linux commands
hi guys

the application guy told me that his server was executing linux commands with some delay...let's say 1-2-3 seconds....

checking the system we found that when the delay took place CPU usage for that command in top was 100%.... this happens for bash, chkconfig, w, df, du among others in fact when you start working with command load average is normal and after executing commands load average is the double amount

has someone seen this before? a know issue?
something to check?


important to note is this the Red Hat Release is 5.4 Beta which I think is not good but the system was working fine until last week
by the way is it recommended to upgrade from Red Hat 5.4 Beta to 5.4 final release? or even 5.5?

thanks a lot guys

Never a good policy to stay on a beta. I would at least upgrade to RHEL5.4 but preferably to RHEL5.7.
