I'm having trouble with zombies. Red Hat 7.1 on a Dell server with 1 GB memory. The following ps output shows a somewhat typical output. Sometimes there are no zombies, but most of the time there are several, and often as many as this. Performance often seems sluggish, and I am assuming that this is because of this problem, though I don't know that for sure. Turning off the database lowers usage and decreases the number of zombies, but I don't know if this is due to the database or to the lower usage.
I can't figure out what is going on. Any help / suggestions would be much appreciated.
[...] check http://perl.apache.org/docs/1.0/guide/performance.html#Forking_and_Executing_Subprocesses_from_mod_perl in particular http://perl.apache.org/docs/1.0/guide/performance.html#Avoiding_Zombie_Processes my guess is that you use fork or its variations which leaves zombies.
