| I haven't followed this thread closely..... amqrmppa is the pool process that holds a pool of connections for the listener. As these processes get full (the about 64 threads comment above), a second one is started. If you see these processes 'eating up memory', then my guess would be that you have a bunch of client programs that aren't issuing a MQDISC. Have you tried issuing a 'netstat -a' to see what it shows? Are you sure that your clients are MQDISC'ing? |

What do I look for in the netstat -a output? I did a netstat -a |grep 1414 which is one of the port my queue manager is listening on. It shown a bunch of "ESTABLISH" and "TIME_WAIT". I suspect this is normal, isn't it?
I asked my client about MQDISC, and they said they did issue this command in their application.
We had 4 queue managers for 4 different applications, and they all behave the same, lots of amqrmppa processes are hanging around. This leads my thinking that there is something missing in the setup or maybe a MQ bug?????
Thanks,
Mimi

Always? Under every error condition? Under every good condition?

| I have seen this condition happen also on my AIX hub. One thing I suggest doing is to clean any extra processes up in you queue manager start scripts not just amqrmppa but all that should be killed. |

mimi,
I'v already seen similar on a Solaris box  and the problem was caused by the TCP settings (correctly: default values). You can tuning the TCP subsystem with ndd command.
Just an example: I see you switch on the TCP/KeepAlive in qm.ini but this is effective only after 2 hours, the default tcp_keepalive_interval. Visit this site for more information: http://www.sean.de/Solaris/soltune.html
Recommended setting on:
- tcp_keepalive_interval
- tcp_time_wait_interval

Hello all,
I encountered a similar problem which was resulting in orphaned amqrmppa processes. The cause is something that has annoyed me about WMQ for some time now.
If you look in /tmp, you will see files named MQSeries.#######, where the # corespondes to the PID of an MQSeries channel handling process, (runmqchi, amqrmppa, runmqlsr). These files are "local sockets", (named pipe?).
The heart of the matter is this: MQSeries needs these files for IPC purposes. If you delete them, you will end up with orphaned processes.
In our case, we had a skulker process which removed files from /tmp after they reached a particular age...
The same may be happening to you. |
