Env: Solaris 5.8, WMQ 5.3 (CSD05).
I have been seeing recurring instances of TCP/IP errors being logged on my queue managers:
Code: |
-------------------------------------------------------------------------------
09/29/04 03:30:39 PM
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] 10 seconds call was 11
(X'B'). Record these values and tell the systems administrator.
----- amqccita.c : 3075 -------------------------------------------------------
09/29/04 03:30:39 PM
AMQ9999: Channel program ended abnormally.
EXPLANATION:
Channel program 'TO.AR1' ended abnormally.
ACTION:
Look at previous error messages for channel program 'TO.AR1' in the error files
to determine the cause of the failure.
----- amqrmrsa.c : 467 --------------------------------------------------------
|
According to the docs I can find, the error 11 equates to "EAGAIN" or "No more processes". However, I do not have any events logged in system level files.
Has anyone else seen this with any frequency? Is there anyway to link these MQ errors to system events? |

If there are client connections to the server and if they exit using Ctrl C, that might cause this error.
I have seen this error in /var/mqm/qmgrs/QMGR/errors and I didn't have any problems with MQ until now (touch wood). |

No client connections. All applications that connect/use MQ run local and use direct server bindings.
The channel connections are to other cluster queue managers. |

Hi,
How do you know that 11 (X'B') corresponds to "EAGAIN" any link, please let me know
I searched in google giving 11 (X'B') but could not get any help.

On Solaris the codes are in /usr/include/sys/errno.h:
# grep 11 /usr/include/sys/errno.h
#pragma ident "@(#)errno.h 1.20 00/02/14 SMI" /* SVr4.0 11.18 */
#define EAGAIN 11 /* Resource temporarily unavailable */
Cheers
