DpRTmPrepareReq: network error of client <T60_U22222>, NiBufReceive (-6: NIECONN_BROKEN), dp_tm_status=DP_LOGGED_IN

*** ERROR => NiHLGetHostName: NiPGetHostByAddr failed (rc=-1) [nixxhl.cpp 503]

*** WARNING => DpAddrToHost: Disabling reverse name lookup [dpTerminal.c 1704]
DpRTmPrepareReq: client address of <T46_U11111> is 0.0.0.0(0.0.0.0)
***LOG Q04=> DpRTmPrep, NiBufReceive (<11111><RFC-JOB> <60> <saptermi01> ) [dpTerminal.c 706]

DpHdlSoftCancel: cancel request for <T60_U11111_M0> received from DISP (reason=DP_SOFTCANCEL_NO_REASON)

Due to the network error of client <T60_U22222>, the session <T60_U22222_<Mode>> is supposed to be closed by dispatcher. 
However, the dispatcher close the unexpected RFC session <T60_U11111_M0>.

Actually, the user <11111> (<RFC-JOB> ) is not a Gui-logon user.
It just looks like a GUI user coming from terminal <60>.

Meanwhile, you can see the incorrect session information in system log.
