[horde] Memory Leak

[Dominaux, Craig C]

Hi All

Over the summer I recently upgraded Horde and applications to the latest
production release

Horde 3.1.3
IMP 4.1.3
Kronolith 2.1.2
Mnemo 2.1
Nag 2.1.1
Turba 2.1.2

Since the upgrade my httpd process are climbing to 100M RES in size and
overloading the server until it crashes.
My Web Server is a 4 proc box with 8GB of RAM. 

Now I can't be for certain horde that is causing this but I've tried
running PHP-5.1.2 with Apache 2.2.0, PHP-5.0.4 with Apache 2.0.55, and
finally PHP-4.4.4 with Apache 2.2.0   all of these combinations have
memory leaks.

If anyone has seen this or know where I can start looking is would be
much appreciated.

Thanks,

I have a test server identical to the one above with no noticeable
memory leaks, only difference I cannot get the same user base as
production.
Once there is a heavy user base on the production server that is where
the httpd processes start to climb.
