Hello Experts,
We have IIS 7.5, .NET v4.0 on windows server 2008 R2 with a IIS web logic plugin installed. I have noticed that the website has been giving away a503 - service unavailable error quite frequently. On checking the event logs, I found that the worker process is faulting with the module IISUTIL.dll with an exception code 0xc0000005, the logs are pasted at the end. I have noticed that there is a proxy configured as an application under DefaultAppPool which in turn points to a web logic port of the web server configured under the same host. Every time this happens, I had to start the application pool in order to bring the website up. Is there a permanent fix for this?
Application log:
