After stopping a particular channel we are getting the following error log:
AMQ9213: A communications error for TCP/IP occurred.
EXPLANATION:
An unexpected error occurred in communications.
ACTION:
The return code from the TCP/IP(select) [TIMEOUT] 20 seconds call was 4 (X'4').
Record these values and tell the systems administrator.
What we want to know is the REASON the connection was dropped and how to prevent it!? |

Return code 4 is on some os EINTR(interrupted system call). Do you use exits for this channel?
But this is depending on the operating system.
Look for related FDC's

Does this kind of post count toward Poobah-hood?

When you captured this error from the queue manager error logs (i hope) then what was the 'Program' mentioned out there ?
Because when I see the same scenario I get :-
----- amqccita.c : 3252 -------------------------------------------------------
05/19/09 17:24:15 - Process(2756616.11377) User(mqm) Program(amqrmppa)
AMQ9208: Error on receive from host CDCSN0008F3PHD1 (162.12.76.128).
EXPLANATION:
An error occurred receiving data from CDCSN0008F3PHD1 (162.12.76.128) over
TCP/IP. This may be due to a communications failure.
ACTION:
The return code from the TCP/IP (read) call was 73 (X'49'). Record these values
and tell the systems administrator.
-----------------------------------------------------------------
As it says its because of communication failure. My wild guess is related to the issues with firewalls/network.
Another thing when there is a load on cpu, due to major threads generation. IBM wrote a solution for this, hope you would get a little help on this matter. please find the link given below:
