Also, check the Windows Application Event log for errors from VPOP3, and check the 'EXCEPTIONS.LOG' file in the VPOP3 directory. These may indicate what the problem is.

 If VPOP3 appears to hang at the **Check OutQueue DB** step, then the probable reason is that the VPOP3 OutQueue contains an excessive number of messages, so it is taking a while to validate them. See the [[delete Outqueue messages directly from the database]] article for some things to do next. If VPOP3 appears to hang at the **Check OutQueue DB** step, then the probable reason is that the VPOP3 OutQueue contains an excessive number of messages, so it is taking a while to validate them.

 +====Backup running====
 +If a database backup (eg using ''pg_dump.exe'') is currently running, then VPOP3 will not be able to complete its startup database checks until the backup is complete (due to database locks). You can tell if this is the case by looking for **pg_dump.exe** in the Windows Task Manager //Processes// list. If it is, then stopping and restart the **VPOP3DB** service should cancel the current backup.

 +====Corrupt Bayesian database====
 +The spam filter's Bayesian statistical database is stored outside the main database for performance reasons. This database lets the spam filter analyse message content based on how previous messages were categorised. Occasionally this database may get corrupted (eg after a power failure or disk failure), which can cause VPOP3 to crash on startup. This database is stored in the VPOP3\_database\bayes.ldb directory on the disk. If you suspect this is the problem, you can delete/move/rename this directory and see if this makes any difference. VPOP3 periodically backs this database up, so it will automatically recover from a previous backup if you do this.
