Hi,
We have a long-lived process that has been working flawlessly without any issues for months. Recently, we've been noticing problems where users are not receiving the task notification emails when the process is invoked and upon checking the Admin UI, we are finding that the process has started stalling in the UserService service to Assign Task to a user. When we restart the application server the process works fine without stalling, but after a certain point in time we began getting the stalled processes again.
Has anyone else encountered something like this? Any ideas on fixing this issue? The error is as follows:
