Hi, I'm wondering if anyone has found MQ and the windows Volume Shadow service coming into conflict with each other.

I'm running MQ 6.0.2.1 on Windows server 2003. This morning I found that the QM had stopped overnight. The event view told me that details of the error had been stored in a log file, the details were:

I also noted that the volume shadow service, which is a back up service had been running at around the same time, according to the event viewer.
Thanks.
