[conspire] php and mm memory leak (off-topic?)

We've been having some issues with speed on our forum, and when we  
tried to use mm, we got a memory link as described below. It's a bit  
off-topic, but I really don't know where to ask. If you know the  
solution, or know of a place where this would be more appropriate,  
please tell me.

If you don't know much about computers... this topic probably won't  
interest you much.

Basically... earlier today I installed the mm module on the LUElinks  
server to handle PHP sessions with memory instead of files. The  
installation went smooth, I recompiled PHP --with-mm and changed the  
session handler to mm. After starting httpd back up, most of the  
users could agree that LUElinks responded faster.

After about an hour, though... MySQL stopped responding. A look at  
the server revealed that there was like no memory left to be used. So  
I thought it might be a fluke... so I rebooted the server to see what  
would happen. Another hour or so went by and the same symptoms came  
back. It appeared as though mm was leaking memory somewhere. So I  
rebooted the server once again, and recompiled PHP again without mm,  
back the way it was.

Later today I'll research it more to see if I can figure out what was  
going on... because mm definitly provided a performance increase.
