Ok, I've played around a bit on my testing server. The error message appears each time a generic agent is added or is running. Before I added generic agents I was not able to reproduce the error on the teting server. Maybe this helps us to get one step closer to the solution :) - Timo Wed Sep 30 16:26:10 2009][Notice][Kernel::System::GenericAgent::JobAdd] New GenericAgent job 'Auto-Close Junk' added (UserID=6).
