The easiest way to reproduce is to:

- start a target
- on initiator, log in and "dd if=/dev/sdX of=/dev/null"
- on the target, try to remove this connection

Most likely, with a target like this:

Target 3: iqn.2007-02.net.syneticon:superthecus.test
     System information:
         Driver: iscsi
         State: ready
     I_T nexus information:
         I_T nexus: 3
             Initiator: iqn.2008-01.net.syneticon:server.vmware5
             Connection: 0
                 IP Address:

You will use this command to remove the connection:

# tgtadm --op delete --mode conn --tid 3 --sid 3 --cid 0

Which will output in syslog:

May  6 17:05:35 superthecus tgtd: conn_close_force(230) close 3 0
May  6 17:05:35 superthecus tgtd: conn_close(89) already closed 0x9e5288c 4

And connection will not be removed.
