@cho-regin The issues looks to be in the same area targeted by the recent fix https://github.com/OPCFoundation/UA-.NETStandard/pull/2714 Can you confirm ? If not please provide also the call stacks.

The fix you mentioned looks like it would fix this issue. I've only run into this deadlock once so I don't think I can reproduce.
