Hi,
The MQ Series 5.3.0 is configured on Sun Sparc Solaris 8 and it was working fine but all of a sudden below error messages are pilling up in log file. I would appreciate if someone can give the solution.
EXPLANATION:
The maximum number of channels that can be in use simultaneously has been reached. The number of permitted channels is a configurable parameter in the queue manager configuration file.
ACTION:
Wait for some of the operating channels to close. Retry the operation when some channels are available.

AMQ9999: Channel program ended abnormally.
EXPLANATION:
Channel program 'XXX ended abnormally.
ACTION:
Look at previous error messages for channel program 'XXX' in the error files to determine the cause of the failure.

AMQ9513: Maximum number of channels reached.

Well in your QM.ini you need a channel stanza
CHANNEL:
MaxActiveChannels=300
MaxChannels=300
The 300 can be whatever number you want default is 100
I think queue manager restart is also required for these to take effect

Hi,
After modifying the channels in qm.ini, the below errors are getting logged in the log file.
EXPLANATION:
An error occurred receiving data from X.X.X.X over TCP/IP. This may be
due to a communications failure.
ACTION:
The return code from the TCP/IP (read) call was 131 (X'83'). Record these
values and tell the systems administrator.
----- amqccita.c : 2708 -------------------------------------------------------

AMQ9208: Error on receive from host X.X.X.X.
Regards,

$ grep 131 /usr/include/sys/errno.h #define ECONNRESET 131 /* Connection reset by peer */
ie. the other system killed the TCP socket session (for some unknown reason)
