We have problem with Application pool recycling process. We have our production site with hosted in IIS version 10. We have used separate application pool for our production site. This application pool getting recycling every 1740 mins by default. The problem is once recycle process started our application is not responding. Seems its usual thing it takes some time to start with new process. But our case it takes around 15-20 mins to getting the palliation up or recycle process to complete. After 20 mins only our site coming up. Seems this time interval is unusual. How to troubleshoot this problem? Is there any problem in application level or server or application pool configuration level? Please help to identify the cause, we couldn’t find the solution to address our site down problem.
