Subject RE: is this normal??
Date Thu, 02 Jan 2003 19:58:04 GMT
I found a trick that might help: up your sar reports to take a snapshot
every minute. Then, when you notice the CPU pegging, go through the sar
reports for CPU usage and try to find the minute that they start. Then,
you can go back through the Apache access logs (mod_jk.log perhaps),
etc. to see if you can correlate a specific request with the the
problem.

Good Luck,
