Ubuntu Linux Apache Error: [notice] child pid XXXX exit signal Segmentation fault (11)

I received the below error when troubleshooting an issue reported to me by a client regarding one of their intranet web sites not working properly. After some poking around I noticed that there were numerous segmentation faults being reported in the Apache error logs. I had previously set up the server to dump core files when there were segmentation faults within Apache so troubleshooting the error was fairly easy. It ended up being a connection issue with an AS400 that was down over the weekend at the company and I was able to verify this using the below information.
