Installed a fresh install of php-4.4.1 and the only compile options were --with-apxs2 and I am running apache 2.0.55 on FreeBSD 5.3 and when I run SquirrelMail version 1.4.5 httpd takes alot of system resources and is really slow.  I can provide more info if nessary.

I have the same problem, but running on apache-1.3.34 (Linux), with the php-4.4.1, i am back to php-4.4.0 and this fixes.
Here is the phpinfo()

Squirrelmail is 1.4.5, can browse all pages, but the problem  appear when open a message.

Another problem is that httpd takes many more seconds to stop with 4.4.1, not with 4.4.0.

I haven't managed to discover if this is a SquirrelMail bug or 
a PHP bug, but the change from 4.4.0 to 4.4.1 definitely 
causes the break down.

A bug report with a work around is available at SquirrelMail's 
sourceforge page.
func=detail&aid=1344216&group_id=311&atid=100311 .  The work 
around is to turn on server side sorting (in your config.php 
file) to prevent the effected function from being called.

I have the same problem. SquirrelMail is taking a lot of CPU since 4.4.1 and timeouts.

I've got a backtrace with gdb when it timeouts :

I don't think it is a SquirrelMail issue because it would seem that other scripts are experiencing the same type of problem
