From the System Configuration page > Diag Log > CSAlog file I get the following: (I'm not even sure this is the right Log file to be looking at? If there's another log file, please let me know and I'll post it.)
[2006-02-09 08:40:09.687] [PID=520] [Csamanager]: Warning: It took 4 seconds to process the last batch (1) of events. Last event: type=EVTM EvSrcComp=13 EvDst=1 EvDstComp=7 EvCode=APCR_ALLOW EvPInt=601 EvPString:30:C:\WINNT\system32\services.exe EvPString
Most likely the problem is in CSAuth - usually is!
Try looking in the CSMon csv (system monitoring) to see if test authentications were still working. If there are what appear to be failures, look in the csauth log file (auth.log) for the same time period.
Could be an exception inside a critical section causing internal deadlock. So try searching all the logs for "exception", "too busy", "worker thread" and see what you get.
