Sudden increment in thread count of the gateway after restarting the CP node

[nelkon]

Description

If the CP is down, and the gateway is constantly trying to connect to the CP, the thread count can be increased. Even in the logs, there were multiple connectivity errors. But, once the CP is up and running again these unwanted threads in the waiting state should be cleared from the memory. However, we could see those threads never get cleared from the memory until the gateway node restarted again. it continues to stay in the memory for days.

Steps to Reproduce

• Create a setup. (One CP and One Gateway)
• Profile both CP and GW.
• Start both CP and GW.
• Wait for 5 minutes till the servers settle down.
• Collect the thread count and thread dump.
• Stop the CP node.
• Wait 15 minutes and collect the thread count and thread dump.
• Start the CP node after 15 minutes.
• Wait for 15 minutes and collect thread count and thread dump.
