Dear Guys
Thanks and apprecite your quick replies
By the way i had stated solving the problem of almost 100% CPU utulization
starting everyday at 4 am and ending at 10 am in a very crude way
top was reporting 95% wa
i started to check the crontab file and noticed that the
cron.daily entry in the file sarts at 4 am
and in the directory i found
-rwxr-xr-x 1 root root 133 Jul 6 16:59 00webalizer
-rwxr-xr-x 1 root root 379 Jul 6 17:02 0anacron

-rwxr-xr-x 1 root root 114 Jul 6 17:01 rpm
-rwxr-xr-x 1 root root 290 Jul 5 21:24 tmpwatch
i started movies some of thes files to difereent directory and finally
found that it was the below file that was the culprit
-rwxr-xr-x 1 root root 290 Jul 5 21:24 tmpwatch
-------
the contents of the file was
/usr/sbin/tmpwatch -x /tmp/.X11-unix -x /tmp/.XIM-unix -x /tmp/.font-unix \
-x /tmp/.ICE-unix -x /tmp/.Test-unix 240 /tmp
/usr/sbin/tmpwatch 720 /var/tmp
for d in /var/{cache/man,catman}/{cat?,X11R6/cat?,local/cat?}; do
if [ -d "$d" ]; then
/usr/sbin/tmpwatch -f 720 "$d"
fi
done
----------------
now everything works fine without this file in the /etc/cron.daily directory
so the tmpwatch was the culprit cause the CPU wait state to almost 99 %
for almost 6 hrs
but jus would like to know if this particular script has any signifance or
any perfomance issue and my system will run perfect without the file
apprecite you help
regards
Fabian
man tmpwatch shows that this is designed to cleanup tmp directories -
you may want to see why your tmp files are either very many or have some
other issues
