Hi All, After a few more errors, i think we might have found out what the problem was...
We have about 500 virtual sites being run on the server... each one of them had its own access and error logs... and we had started running into a "too many open files" problem... i have removed "separate logging" from many of the virtual sites... (just logging to a central spot now)... things seem to be better.... :-) simran.
