SYMPTOMS

The recovery mechanism in JET may incorrectly advance the checkpoint under certain circumstances. If JET is started and finds that the database is in an inconsistent state, JET attempts recovery. If the database is locked open for some reason (by another process such as a backup program), JET receives an error -1032 (Jet_errFileAccessDenied), but does not handle the error properly. JET continues to try to play forward the logs into the database and increment the checkpoint file.

The following events may be observed in the application event log:

WORKAROUND

The workaround for this issue is to remove the file lock on the database, which is usually caused by a backup program actively backing up the database. Do not run file-level backup programs against the Exchange Server database when the database is running. Stop the Exchange Server services first. The recommended backup method is to use Exchange Server-aware backup programs to do an online backup.
