Hi I have application on Windows 2012 R2 server and with IIS 8.5. This is the only application hosted on this server. Job of this app is to after assertion it redirects to my application portal in another server.
Once in a month IIS stops responding a i'm receiving the below error in event-log only once
The description for Event ID 18 from source SiteMinder Agent cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Web Agent version: 126.96.36.1999
During error if i try to hit the url it throws me 500 error in the browser. If i reboot the server everything becomes normal.
Please guide me fix this issue
I am unsure what that error means. But here is what I'd do, if we are sure that it reoccurs at a regular interval.
Enable WebAgent Tracing
Enable IIS Tracing.
Tracing | Microsoft Docs
Collate the logs and stats. Then try to see if we could derive a pattern.
It looks to me that LLAWP is crashing.
I would suggest capturing the crash dump along with the other logs that Hubert suggested above.
But crash dump is probably the most crucial here.
You can configure it to capture crash for LLAWP.exe and/or W3Wp.exe
