[Xymon] Xymon Internal Server Error

Greetings all,

I have Xymon 4.3.5 running on redhat 5. It has been working fine for quite some time. Around 3am this morning, the webpages display "internal Server error". I looked at the apache logs and Xymon logs and do not see anything that is wrong or that could be causing this. Any help would be greatly appreciated.
