Umm, it seems to me that it's tgtd itself:

# tgtd ; tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2008-01.....
tgtadm: can't connect to the tgt daemon, Connection refused
tgtadm: can't send the request to the tgt daemon, Transport endpoint is not connected

Lets wait a second, and try again - it succeeds:

# tgtadm --lld iscsi --op new --mode target --tid 1 -T iqn.2008-01....
#
