[CentOS] Memory Leak with stock Squirrelmail, PHP, mysql, apache since 5.3

Hi list,

We are experiencing a memory leak on our SquirrelMail server since the 
5.3 update.
The server is fully updated, only stock rpms. The httpd processes are 
eating all the memory and after swapping like hell, the server became 
unresponsive and we must hard-reboot it.
The server is not that much loaded (max 10-15 concurrent users but with 
tons of mail in their inbox). Configuration's speaking, nothing was 
changed before and after the update.

Is there someone else experiencing the same thing ? How can I search 
deeper the origin of the leak ?

Thx,
kfx

Details follows:
