I found a directory called "otrs/var/log" with various ".log" files but nothing after October 2008 and mostly composed of files with names starting with "LoopProtection" followed by the date and endiong with ".log" and consisting of what seem like the usernames of the people logging on to the system??!!

I ?think? The system log is stored as /var/log/otrs. No where near our box or I'd verify first.

the system log!
