TSM 6.3.3 on Win2K8-64
Exchange 2010

Two Exchange nodes in a DAG, each with multiple active mailbox DB's, running 
TDP for Exchange 6.4.0.0, TSM client 6.4.0.0.
(The passive DBs live at a DR site across a WAN, which is why I'm backing up 
the active ones.)

TDP Scheduled backup ran for a couple of weeks on both nodes with no problem.
Full backups only so far, as the DB's are still in circular logging mode.

2 nights ago the backups started failing on one mailbox on node A, and one 
mailbox on node B with:
ACN6076I < databaseName > cannot be backed up because its 'BackupInProgress' 
flag is set to 'True'. Check whether the database is being backed...

But there is no other TSM backup in progress.  The Exchange utility getmailbox 
shows the "backup in progress" flag is indeed set to "True".
Diskshadow shows no leftover shadows.
I found this hit that says we are essentially toast and will probably have to 
reboot.

So my question is, what causes this situation and how do I prevent it happening 
again?
