Media server hard locks during backup or duplicate jobs to a deduplication folder

Problem

Media server hard locks during backup or duplicate jobs to a deduplication folder

Error Message

None.  The server hard locks without generating an event log message

Cause

The PDVFSService.exe terminated unexpectedly.  During the process of shutting down the PDVFSService, the PDVFS driver (pdfsd) goes into a loop trying to cancel outstanding I/O requests resulting in the system locking up.

Solution

This issue is not commonly encountered.  But once encountered, seems to happen every few weeks on the media server.

This issue is resolved in Backup Exec 2012 Hotfix 180962
