Hi All,
I am seeing multiple amqrmppa processes running on my queue manager QMXXXXXX. And, all these processes are of few days/weeks old.
I think there should be only one amqrmppa process on a queue manager and if there are multiple they should not be older by few days.

mqmuser 450702 282790 1 May 20 - 824:05 /usr/mqm/bin/amqrmppa -m QMXXXXXX
mqmuser 614434 282790 0 Aug 18 - 26:16 /usr/mqm/bin/amqrmppa -m QMXXXXXX |
Can anyone suggest me what is the reason for all these multiple instances of same process. |

Because each amqrmppa process can have up to 64 threads. If you have more than 64 channels running at any given time, a new amqrmppa process will be spawned. When they eventually go away is nothing to lose sleep over.

does it mean in my case as there is 3 amqrmppa processes are running, so the number of channels running is more than 64+64+ |

No.
It means that the number of channel instances is more than 128. |
