We have been periodically receiving errors similar to the following:

2-03-2006 10:20:22 am: COMN-3.23-180 [nmID=A0022]
NSS-2.70-5008: Volume SERVER_SRV2/DATA_SV had an error
(20012(beastTree.c[510])) at block 14565995(file block -14565995)(ZID

NSS-2.70-5009: Pool SERVER_SRV2/20060203102018 had an error
(20012(beastTree.c[510])) at block 14565995(file block -14565995)(ZID

Sometimes we are also receiving a message that the pool is being

We have archive/versioning installed on this server. Versioning is set up
to use the snapshot feature. The error is occurring on these short term
snapshots. The snapshot pool is different from the original pool and is
also on a seperate mirrored hard disk. The snapshot pool is the same pool
where the archive volume is located. The server is NW6.5 sp4a, but the
problem was also occurring with sp3. Originally we were getting the error
once a month or so. Now it has happened twice in the last week.

How do I go about tracking this problem down when the pool in question is
only a temporary snapshot pool?
