1. amqrmppa is the listener pooling process and amqzlaa0 is the local agent process.
2. when your qmgr is running on AIX4, these processes are working in single-thread mode (not sure  ). On AIX5 there are tuning parameters for multi-threads.
So your qmgr serves a lot of client connections the number of processes can become to a high. But more investigation is strongly recommended.
HTH,

"MaxChannels, MaxActiveChannels"
I used the default value is 100, I use the
netstat -an |grep 14141 |grep tcp4 |grep EST|wc
to check the maxActiveChannel number.
when the maxActiveChannels achieve 100, then the process number will grow quickly ,why ? I use AIX 4 |

You can check your channel from qmgr's view in this way:
| Code: |
| echo "dis chs(*)" | runmqsc <qmgrname> | grep CHANNEL | sort | uniq -c |
If sum of these number differs from netstat, query a list of non-established connection on listener port. There are a lot of parameters at network level.
