This causing performance issue and have to restart server when it is unresponsive. Kindly provide your inputs to fix this issue.

Hello @AK86 

It seems to be certificate issue.

Ensure that the root certificates used to validate (target) server certificates are up to date. CAs occasionally update their root certificates, and older versions may not recognize newer certificates.
