Hi Prabin,
Attached trace file belongs to a Dispatcher running on instance number 10.
On the trace, we see that it can not connect to Message Server (running on ASCS11, as per GetProcessList output):
..............
*** WARNING => DpMsCheck: no answer from msg server since 284 secs, but dp_ms_keepalive_timeout(300 secs) not reached [dpMessageSer 3392]
*** ERROR => DpMsCheck: Waiting for answer from msg server since 300 secs [dpMessageSer 3371]
*** ERROR => DpMsCheck: Connection to msg server will be closed [dpMessageSer 3373]
***LOG Q0M=> DpMsDetach, ms_detach () [dpMessageSer 2038]
MBUF state OFF
DpMBufTypeMod: MBUF component DOWN (event=MBUF_DPEVT_DOWN).
Check Mssage Server trace file (dev_ms) that should be located on ASCS work folder and attach it.
Thank you.
