RE: Memory usage 1.5.5

Do you use Collab.nets RPMs? Or Did you hand-build your apache configs?

 

I've been able to get Collabs installed, and I can see that they are
using a newer version of httpd than RHEL5 gives out, and that their
module list is a lot shorter. I'm going to experiment with the configs
for Collab to see if I can get the same level of auth and ssl access
working that I require.

(top posting)

Looks like you have a lot of modules there. Most are probably not
needed,
but I can't say any are causing the memory leak problem.
