Hi Cong,

Your IS is going to hung state due to below issue.

Available Thread Pool Warning Threshold Exceeded: 0% available

You need to check your resources setting and increase the thread count in server thread pool based on your requirement.

Just navigate to Settings->Resources->Server Thread Pool.

Thanks,
Yogesh

Hi Yogesh Bhandari,
Yes, it’s hung because thread pool available is 0%, but that is not root cause. Request not much enough to use all threads, maybe problem come from exception related to DB.
