Weird issue after upgrading.

Here's the breakdown: Machine is a webserver with FreeBSD 4.8 Stable, Apache 1.3.3 I upgraded PHP from 4.3 to 4.4.0 Ever since I upgraded have been having intermittent problems were sometimes you have to click a PHP page 3-4 times to get it to load, other times you get a "cannot find server" error in I.E. or a blank page in FireFox Normal HTML pages work fine. Also started getting a "exit signal Floating point exception (8)" error in the logs since the upgrade. SSL is acting weird too, again ONLY with PHP pages - getting an intermittent "terminated unexpectedly" error All dependicies and ports have been upgraded also (Zend Optimizer, etc). ANy ideas or help is greatly appreciated.....this is a very powerful machine, load averages never go above .22
