Shared Server : Application pool stops intermittently

Question

There are 400+ websites that have been set up on the shared server. The application is developed in asp.net with framework 4.5.

The server OS is Windows Server 2019 and it has 4 Core CPU, RAM of 170 GB

It is observed that the application pool stops intermittently with any website randomly. The CPU utilization is not more than 10% and only 70-80% of memory is getting utilized.

What could be the possible checks and resolutions to prevent the app pool stops working intermittently?

Answer 1

@Kiran K,

There are many reasons for this issue, usually since the w3wp.exe worker process, created by IIS to execute a web application, is crashing frequently, the respective IIS application pool is turned off. evidence of repeated w3wp.exe crashes may be found in Windows Events, in the System log with Source=WAS.

Besides, app pool recycling can also cause this issue, so please check your app pool recycling settings.
