Connection reset during workflow after stage is complete. pika setting is probably still needed #137

Closed Weiming-Hu closed 3 years ago

Weiming-Hu commented 3 years ago

I have experimented with the workflow without pika settings, specifically without the following two lines in my user code:

pika.connection.Parameters.DEFAULT_HEARTBEAT_INTERVAL = 0
pika.connection.Parameters.DEFAULT_HEARTBEAT_TIMEOUT = 0

But then I got the following error in my client-side sandbox:

During handling of the above exception, another exception occurred:

When I added back those lines to my user code, things are working again. I suppose there are still some leftover issues with pika?

Thank you

@Weiming-Hu , can you confirm your radical-stack?

This might have to reopen this: https://github.com/radical-cybertools/radical.entk/issues/509

Sure thing. Please see below:

Thank you @Weiming-Hu , can you try again after you update entk to v1.5.12? The actual versioning got complicated like radical.entk : 1.5.12-v1.5.12@HEAD-detached-at-v1.5.12 but you should have updated pika handling if you see 1.5.12 in the radical-stack.

Weiming-Hu commented 3 years ago

Got it. Please let me try again with the updated version and I will make sure to report back here. Thanks.
