Event ID VSS 8194, Windows Server 2012 Hyper-V Cluster

Hi,

We have 10 blades Dell M620 in M1000e CMC, all are windows 2012 hyper-V cluster members configured with iSCSI software initiator, HITKIT 4.7.1 with latest FW and drivers to date. Windows also fully patched.

Storage: Dell Equallogic PS6110 (5 boxes),

CMC Switches: Force 10 dedicated to iscsi traffic

Issue: Getting so many events (VSS 8194). how to get rid off these errors and is it harmful for cluster stability, we had so many crashes with unknown cause!

Today we had another crash, one blades got blue screen and restarted, following are the output of MEMORY.DMP.

Probably caused by : msiscsi.sys ( msiscsi!iSpProcessSessionIdle+4b )

Urgent help will be appreciated!
