Please check info placed in this email.      Mar 9 08:29:15 kabuki07 kernel: connection1:0: detected conn error (1020) Sort of a new problem maybe. It looks like the target is dropping the connection on us here. It might be that the target thinks we have screwed something up. Do you see anything in the target logs? Maybe something about a protocol violation or something about a bad pdu or bad command or something being formatted incorrectly?
