I had a fast experience to increase the performance of PHP scripts in about 100%. Fast, but unhappy. The problem is the following one: when using PHP with Sessions being recorded dinamicaly with module MM (session.save_handler = mm), after some minutes of activities (about executed hundreds of scripts), start to appear ackward messages in apache's error_log, as:  

[ Tue Feb 25 15:45:14 2003 ] [ notice ] child pid 1340 exit signal Segmentation fault (11)

... and in few minutes later, apache crashes. 

Some solution? I'm looking for and I did not find nothing... I arrived to read something about create the file /tmp/session_mm.sem but... the problem continues  repeating.  

Unhappyly I had that to come back toward the traditional method, using files.  

I don't know if this problem is on PHP, Apache or MM, but.. I know it only appears when I change the method of sessions be saved.

Some solution?  I looked for in the InterNet and I did not find nothing... I arrived to read something it type to create the archive in/tmp/session_mm.sem but... the problem continues if repeating.  

Unhappyly I had that to come back toward the traditional method, using files.  

Using: Apache 1.3.27, PHP 4.3.1 and MM 1.2.2
