Deduplicationcache.exe hangs and causes Journal archiving to stop
Does anyone know if there is a problem with deduplicationcache.exe that would cause it to hang and prevent journal archiving from happening?
Journal archive was not happening and the journal mailbox built up to 16K items this morning. In the DTRACE log, I saw the mapi mutex processing the mailbox already messages but no errors. I stopped and restarted the journal service but journal archiving still wouldn't start. I stopped the journal service again and used task manager to kill deduplicationcache.exe and then restarted the journal service and now the journal mailbox is being processed.
We are using EV 5.0 SP5 on Windows 2003 and the Journal mailbox is on an Exchange 2003 server.
