Re: memory leak in FBSD 4.4-STABLEI already did that on the boxes and the configs are identical.

Well at any rate here's something you can do to keep you box stable until a real solution in found. Update the MaxRequestsPerChild directive in the apache conf. This may be at 0 where a child process will never die. Set it to something like 100 so the child will die after it serves 100 requests.
I would go through the config and compare everything in the first section on the 2 different servers.

This is after about 20 minutes of running. given 3-4 hours they will be about 10 megs each.
This is the 4.3 system after 1 hour of uptime:

Any ideas?
Yeah, I'd check what versions of apache are you running ? You theory doesn't hold much water unless the version are the same. I would also check to see what sort of memory configuration you have for apache.
