The Secure ACS v3.3 is dual homed on Win2003 Servers. It runs normally everyday but a few days it failed responding to authentication and went in "hung" state.
Tried restarting the ACS service didn't help. The only fix found to be rebooting the server.
ACS logs following message everyday around 23:00 but I am unable to find "the" configured process that suspends CSAuth service.
"Service CSAuth has been suspended for a configured function to proceed.
Monitoring will suspend until the service is restarted."
