Hi, in our worker application I see several threads in WAITING state, for workflows that already completed, like this one.
Do you know how to avoid this? Thanks!
This is part of the output from jstack:

In this case, for example, the activity method is update. From the Temporal UI, I don’t see any problem in the call to this method.
