So do your diligence and find and describe the pid tree to get to that process.

It will become so much more clearer...

amqzxma0
This is the execution controller (EC) process, which is the heart of a queue manager. There is one per queue manager. When an application issues an MQCONN, a shared memory message is sent to this process to identify a handler agent process and it may launch a new agent for this request. All other queue manager system processes are child processes of amqzxma0.

Why? What ill effects are you seeing? Why are you interested?

In normal use, any of the AMQ* tasks are managed internally.

We use MQ for iSeries. We tried to execute a STRMQM and this command didn´t response (this problem is related with qmanager's journal, MQ didn`t recover any information from it), immediately the AMQZXMAX run, and it was using 65% of CPU. While the AMQZXMAX process was running we couldn´t execute any MQ command on another qmanager. The MQ was freeze. When we killed the AMQZXMAX process, MQ returned to the normally.
