Pinned topic Some WAS Port Listeners fail connect to MQ using client connection

‏2013-02-24T22:07:31Z |
What could limit the number of client connections from WebSphere Port Listeners to MQ Server?
In WAS I setup around 24 Port Listeners with same Queue Connection Factory using client connection for a remote MQ server using a svrconn channel.
1/3 of listeners would start fine, but the rest are getting this:
<<
AMQ9204: Connection to host 'host(1414)' rejected.
AMQ9558: The remote channel 'CH_SVRCONN' on host '' is not currently available.
>>

MQ server is version 6.1 and not sure which configuration would determine the channel limit or how to check.

Any help or suggestions greatly appreciated.
thanks.

    added this in qm.ini file and it did make a difference.

    CHANNELS:
    MaxChannels = 200

    Either the value or the fact that i restart MQ Queue Manager. There was no such entry, which i thought would default to 100 channels, that should be enough for 24 listeners each one single threaded...

    Can you please let us know the Completion Code and Return Code showing up in the application log for the failed client connection?

    I assume these are CC and RC in following
