SUMMARY: CPU utilization gives spikes in every 5 min.

Hi All;

Thanks a lot for all who replied. Finally the problem was fixed by
applying latest patch.

I am sorry for delay in posting as this machine was huge and I took
these many days to actually apply the solution.

Good day.

Thanks & Regards;

Look into your cron entries to be sure that some clever user isn't
