Database problems
If you get database problems, the following error events are generated in the Windows Application event log (event source UserLock):
- 500: A logon/logoff event was not inserted. Check the description to understand the reason.
- 501: The service was not able to connect to the database. Check the description to understand the reason.
- 502: The server is probably overloaded and too many events are waiting in the queue for insertion in the database.
