MQSeries.net :: View topic - runmqchl hanging even after stopping the channel

Hi All,

We have a server - Requester channel and channel exit on the requester channel which modifies all my incoming messages and sent it to the local queue of the destination queue manager. Server channel in source queue manager and Requester channel in Destination queue manager.
Channel exit has one global variable loaded with some values in its initialization and the variable is used to modify all the incoming messages. When the channel exit terminates it frees the global variable buffer(pointer) as well as local pointers.

I am starting my server channel and then my requester channel. Now I am able to see the runmqchl running for my channel for destination queue manager.

$ ps -ef | grep runmqchl
mqm 17019 10569 0 12:50:09 ? 0:00 /opt/mqm/bin/runmqchl -c <channel name> -m <QM name>

Stopping both the channels and the status showed as "STOPPED" but runmqchl is still running.

The failing process id is nothing but runmqchl process id. This error log from /var/mqm/errors.

When i start again i am getting one more runmqchl for the same channel.
$ ps -ef | grep runmqchl

mqm 19822 10569 0 12:57:24 ? 0:00 /opt/mqm/bin/runmqchl -c <channel name> -m <Destination QM>

mqm 17019 10569 0 12:50:09 ? 0:00 /opt/mqm/bin/runmqchl -c <channel name> -m <Destination QM>

Channel status is RUNNING and I am able to send message successfully and the channel exit process it successfully and sends it to the local queue of the destination.

Now If I stop the channels , Requester channel goes in to STOPPING status..
