Mike,
we have done the following two commands. Please find attached the
output files.
tcpdump -i eth0 tcp port 3260 and host
192.168.192.136
-w /root/tcpdumpIPandPort3260.dump
tcpdump -i eth0 host 192.168.192.136 -w /root/tcpdumpIPandNada.dump
Checking these files with wireshark, an error found is "TCP Previous
segment lost iscsi-target". It looks like a network problem.

It seems like the target is not liking something we are doing.
Could you take a trace with wireshark/ethereal so we can see what the
last iscsi pdu that was sent to the target.
