Trouble with segmentation fault/or apache config

[filch]

Hi,

I am having a hard time with a site after having to move servers because of a drive failure on the old one. I have one site that is MySQL driven, for membership, access levels etc. When I try to log in, the server hangs and never does connect. Sometimes in the error log, it says I have a segmentation fault. But sometimes it does not. Id I restart the server whilst it is trying to connect, it then immediately wants to downliad the php file and open it in a text editor.

Segmentation Fault in 20593, waiting for debugger
Segmentation Fault in 21237, waiting for debugger
Segmentation Fault in 21042, waiting for debugger

This server is a bit weird in that, I have two instances of apache running because i have tomcat running on one instance along with another site that needs SSL so it is listening on one IP. The other instance is hosting the bulk of my other sites, but one of those also needed SSL, so it is listening on another IP. Specs:

Server version: Apache/2.2.15 (Unix)

PHP 5.1.4 ( used by both instances of APache)
PHP 4.3.9 ( not sure what this is doing there but perhaps for some older apps written for PHP4)

There also seems to be a YUM install of PHP4 on the server as well ... although both instances seem to be using PHP5. Now the code for this site was written for and working on a server that only had PHP4 on it but I am not sure if this might be causing any issues.

I really could use some help on this as I must have this site fully functional by Thursday morning ... yikes!

Let me know if you need any other info.
