I receive the System Warning more frequently: “A process serving application pool ‘abc’ suffered a fatal communication error with the Windows Process Activation Service. The process id was ‘4864’. The data field contains the error number.”.
I am running an ASP.NET Framework 4 web application on IIS 7 on Windows Server 2008. When access to the website, it raise error message: ‘HTTP Error 503. The service is unavailable.’.
To temporary fix the issue, I have to go to the Internet Information Services (IIS) Manager to start my Application Pool again.
Currently, I’m working around with some resources below:
- How to use the Debug Diagnostics tool to troubleshoot a process that has stopped responding in IIS
- How to use the IIS Debug Diagnostics tool to troubleshoot a memory leak in an IIS process
- How to use the Debug Diagnostics Tool to troubleshoot high CPU usage by a process in IIS
And checking others IIS Application Pool Availability Events
