I had MQ v5.3 with CSD06 installed on a Sun Cluster. There are about hundred of amqrmppa processes are left running over time and they ate up memory. I tried to stop the queue manager but those processes were not ending.
Does anyone know why the amqrmppa processes are left running after the queue manager is stopped? Did I miss anything in the setup/configuration?
Thanks,
Mimi

| How are you starting your listener(s) ? |

I think this is the listener process.
Did you try stopping the listener and see if the processes go away? |

Here is how I start my listener
runmqlsr -t tcp -p 1418 -b 100 -m RCMQ1OL
I tried to end the listener using endmqlsr but I couldn't get it to end, here is the message I got back
No WebSphere MQ listeners found for the given Queue Manager
Is there anything wrong with the way I start the listener?
Thanks,
Mimi

amqrmppa is a channel receiver process. I believe it services both RCVR and SVRCONN Channels.
When you did a ps -ef | grep amqrmppa did you note the Parent Process ID. Were they orphaned. Did you have any defunct processes?
It is not normal for there to be amqrmppa processes if all the MQManagers on the server have been stopped.

When I did ps -ef | grep amqrmppa I noticed that the parent process ID is the listener process ID. How come I couldn't use endmqlsr to end the listener process? I suspect once I end listener process, these amqrmppa processes should end as well, right?

I tried to end all queue managers, kill all listeners and those amqrmppa processes are still hanging around. There were hundred of them and I had to write a script to kill them.

Maybe yu are trying to do just
and it is trying to end the default listener.
You should do
endmqlsr -m RCMQ1OL.
The QMGR should be down before you issue the command
or
ps -ef | grep runmqlsr | grep RCMQ1OL
grab the process id and kill it. |

I stopped the queue manager and ran "endmqlsr -m RCMQ1OL" and got that message.
Sometimes I stopped the listener by killing it. But I think that "endmqlsr" has some other functionality which will end all amqrmppa processes, that's why I try to use "endmqlsr", but I didn't get what I expected.
Thanks,
Mimi

Yes, under normal circumstances one would expect that the endmqlsr command would indeed stop all it's child processes before ending the parent but I suspect these are not normal circumstances.
By default I believe the kill command will behave as if you issue a kill -15 <PID> which will attempt to kill any child processes of the process specified before killing the parent. -9 is the baddie which says kill it now with no cleanup.
under certain circumstances I have had to use the following to stop all mqm processes as root:
| Code: |
| # ps -ef | grep -v grep | grep mqm | awk {'print $2'} | xargs kill -9 |
This is a particularly brutal and messy but affective way of stopping MQSeries and it will terminate all mqm sessions as well.
Buy the way, are you seeing any .FDC files being created in /var/mqm/errors?
When you stopped the MQManager, did you clean up your Shared Memory Segments with the ipcrm command or the amqiclen?

No, I don't see any .FDC file created.
No, I didn't use either ipcrm nor amqiclen. But we did reboot the whole box twice.
Is there any idea how to control those amqrmppa processes? Each queue manager should have 1 amqrmppa process, is it correct? Why the listener process keeps creating these amqrmppa processes incrementally without cleanup?
Thanks,
Mimi

I am having similar problems.
I think each amqrmppa process handles around 64 connections.
On the system with all the amqrmppa processes do you have any full queues.
Could you show your channel definitions and qm.ini files.

| Code: |
# echo "dis ql(*) CURDEPTH MAXDEPTH" | runmqsc
|
If the value of CURDEPTH is the same as the value of MAXDEPTH. That Queue is full.
