Okay, so you have a zombie process problem on your machine, particularly with Apache-related programs. Something I'm curious about, since the RSS of your httpd process is quite large (150MBytes): When you make httpd.conf changes and need to restart Apache, how are you doing it? Are you using "apachectl restart", or some init script which does something similar? If so, I would recommend you not. Apache has a history of having problems with function namespaces being lost or breaking in odd ways after using "restart", especially with mod_perl (definitely confirmed with mod_perl 1.x). The same goes for when adding/removing modules. I always advocate a full "stop" and "start", which is not the same thing as "apachectl restart". Another common one is people sending the main httpd process SIGHUP, which isn't what people should be doing. They should be using SIGUSR1, or "apachectl graceful". Another possibility is logging oddities (if you're using log directives in Apache with pipes, for example -- though those bugs are supposedly fixed...) Those are all of my ideas. Otherwise I'd recommend you hire a good, low-level Linux SA and let them try to figure out what's going on with the system. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
