[Client log] Attached is the client log. The client seems to hang when it tries to close the pool manager.

Obviously, I purposely send large data to max out the NIC to test worst-case scenario. In reality I wouldn’t be sending so much data simultaneously, but I need to implement worst case scenario and know my boundaries.

Are there any errors in the logs?

Does anyone know why this happens, and what exactly the machine is doing what it hangs? (I see a high number of context switching when it hangs).
