java - Intermittent SSL Connection error while connection to Windows Active Directory

We have recently upgraded SSL certificate on Windows Active Directory. After update of SSL certificate we are intermittently getting SSL error while trying to connect Windows Active Directory server from Java Web Application.

Below are the SSL Debug error logs. Strange point is post restart (sometime 1,2 restart) issue got resolved.
