Does anyone have guess as to the typical/usual reason a SVRCONN channel from an MQ Client to Server might experience and unexpected closure of the connection.
It is a Data Power client connection to MQ server. The MQ server error log is below in Bold font. The Data Power showed an MQ failure with a 2009 code (big help!)
07/03/2012 07:18:01 AM - Process(27494.998) User(mqm) Program(amqrmppa)
AMQ9209: Connection to host '1 (1.2.3.4)' closed.
EXPLANATION:
An error occurred receiving data from '1 (1.2.3.4)' over TCP/IP. The
connection to the remote host has unexpectedly terminated.
ACTION:
Tell the systems administrator.

One possibility I can quess at is that the message being consumed by the Data Power is quite large and exceeds some connection time out setting while trying to consume it. I failed to mention that the Data Power is doing a 'get'.
Only issue with that is that when the message is resent it works (so far) every time.
TIA,
GTC

| I'd guess it's the firewall in between the two devices deciding the connection is taking to long? |

That would be a good guess but no firewall between the MQ server box and the DP box. They are both behind the firewall doing local communication.

... that doesn't mean the network guys aren't still monitoring and closing "stale" connections.
Could also be HBINT/KAINT - not as likely, though. |
