The number of events cached for action "MSSQL Database", which has been unreachable, exceeded 8192 events. If this action is no longer in use then you should disable or delete the action so that events are no longer cached. EventSentry will continue to cache events until the maximum size of the temporary backup file "C:\WINDOWS\TEMP\eventsentry_backup_xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
..tmp" (32 Mb) is reached. 133952 events are currently cached, the backup
file size is 32 Mb.
If EventSentry is unable to reach the database, it will queue up events until it is available again.
This message means that queue is full because the database is not accessible by the remote machine.
