Zeeber isn't completing/cancelling tasks

Hello everyone, I’m having trouble with CAMUNDA.

After starting several processes for a few hours, Zeeber started crashing.
The Zeeber Worker isn’t completing tasks, canceling them, or moving the instance. I’m using self-managed Camunda 8.7 with Docker. Does anyone have any idea what’s going on?

It stops the processes that you try to cancel or move as per the attached image:

Do you see anything suspicious in the logs that correlates with the same time?
