Hi, If you have an unstable network, which is dropping packets in a weird way (data is lost, but the connection is still kept alive from the perspective of the underlying operating system) it could happen that task will be perpetually blocked. But this is extremely rare. I would first suggest trying to look in other directions. For example if maybe your Task is stuck/deadlocked somewhere in your code? I would suggest attaching a debugger to the problematic TaskManager and/or gather some stack traces.
If it's indeed a network or hardware issue, a good question would be if it's happening always on the same physical machine? Last time I saw a user reporting a similar problem it ended up being a faulty machine. Best, Piotrek śr., 6 sty 2021 o 17:16 赵一旦 <hinobl...@gmail.com> napisał(a): > I've had a problem many times.
