[Bug] strange workflow task timeout

[hebrd]

I've set the activity timeout to 3600 seconds in the settings. Most tasks complete normally, but some are not polled and executed by the worker until several hours later.

Below is the event history—I'm unsure what happened. Could anyone help diagnose this issue?

Thanks in advance!

Workflow task timeout means something worker side is preventing that workflow task from responding within 10 seconds. It could be any number of things (e.g. blocking the thread in async def functions somewhere in the system such as activities). Event history alone cannot give us enough information about the code. If at all possible to provide a small, standalone replication (even if it has to be run several times to see it or be put in some kind of loop), that could help.

Also, you can use our traditional support methods instead of GitHub if you'd like: https://temporal.io/community.
