Depending on what the queue manager functionality is these processes are running in unix
amqzmuc0 Critical process manager
amqzxma0 Execution controller
amqzfuma OAM process
amqzlaa0 LQM agents
amqzlsa0 LQM agents
amqzmgr0 Process controller
amqzmur0 Restartable process manager
amqrmppa Process pooling process
amqrrmfa The repository process (for clusters)
amqzdmaa Deferred message processor
amqpcsea The command server
The other processes may be trigger monitor processes or application instances linked to the queue manager
I'm not sure but some of the queue managers have a lot of processes. To me even 271 seems like a large number unless u have a lot of triggerred applications |

amqcrsta is a listener process. If you've got large numbers of them I would suggest that you're using client connections & whatever's making these is not disconnecting properly.
You might also find this of value:

This is with the complements of Mr Google, who had a number of other suggestions you might find valuable.

Also, do not forget that on some OSes, with some options...
The ps command will produce a list of threads rather than a list of processes.
So you may see a lot of entries, for a small number of real processes.
