Some debug information about the close issue:

tgtd: iscsi_tcp_event_handler(160) connection closed

tgtd: it_nexus_destroy(265) cmd_hash_list entry 13 not empty
tgtd: it_nexus_destroy(265) cmd_hash_list entry 14 not empty
tgtd: it_nexus_destroy(265) cmd_hash_list entry 15 not empty
tgtd: iscsi_tcp_event_handler(167) connection closed

So it looks like the cmd_hash_list is not actually cleared on a connection
close.

Is there anything more I can do to troubleshoot this issue?
