Instances of ultra tasks stops receiving messages after multiple failures

Hi Team,

We had an issue in Production and I need some assistance from you experts.

I had one pipeline which is very complex one with multiple scripts snaps. And this pipelime receives messages from IBM Mq and we are using ultra tasks with 3 instances.

Now we are seeing when loads of messages are coming in and it has multiple failures, instance gets stopped automatically and gradually stopped picking up messages from MQ. Though ultra tasks is enabled, but instances automatically get a stopped.

Them we have to manually stop and start the tasks, and we see messaging again starts flowing. We are experiencing this when we have loads of messages coming in.

Can someone suggest a solution out here. Seeking urgent help.

Regards
