What are the symptoms of the problem? How did you manage to get that 
log? Why it doesn't contain the timestamps? Where in it the pairing 
"Warning" message for "Suspicious CDB" one? Why there are a lot of 
messages about closing connection and there are none about creating them?

The RESERVED_TAG tag message has no relation with RESERVE/RELEASE 
functionality. It means that VMware sends TM command with forbidden by 
iSCSI RFC Initiator Task Tag value or the iSCSI header was for some 
reason corrupted.

Can you reproduce that problem and send me the *good* log together with 
the corresponding network dump for the following two cases:

1. In the current configuration

2. With header digest enabled
