cpu / memory intensive children
|
|
I've got a single point 3 machine cluster: Things work well for the most part, but
I've noticed that (in 'top') some of the apache children are substantially larger
than all the others after only a few reqests; most hover around 5M (normal), but
others grow wildy up to 20,30, even 50M. This instance handles static content and
ssl, along with being the backhand decision maker.
When one of these fat children field a request, they grow quickly in memory and the
cpu pegs. When the lighter (healthy?) children handle a request the performance is
great and the cpu is totally fine.
Software:
Solaris 8, Apache 1.3.12 (old, I know), static backhand, raven ssl. Apache was
compiled with a shared core. The binary shared via NFS.
A typical directe (pretty straight forward)
<FilesMatch "\.(cgi|pl)$">
Backhand removeSelf
Backhand byAge
Backhand byLoad
</FilesMatch>
I doubt that the above could contribute to this problem, but I've included it just
in case. If anyone out there has some ideas I would appreciate it greatly.
Regards,
Matt
