RE: Memory usage 1.5.5

[Adrian Marsh <Ad...@ubiquisys.com>]

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.
