IIS 8: websites troubleshooting

MeSrp 1

Hi ,

We have iis 8 server with 15+ websites hosted in it and suddenly all websites are not loading.
I checked all the permissions and DB side no issues over there but in workerprocess tab i see long running process with
verb -Get
state -Beginstate
modulename -IIS web core

Tried killing these process and when I hit url it shows same process again.
Attached screenshot.

Help me to solve this issue

Thanks

Hi @MeSrp From the screenshots you posted, there is no way to get helpful information, you can try to use failed request tracking to see which request has a problem.

Hi Sam

I tried Failed request tracing but no luck.
App is not at all loading, no iis logs, no event viewer logs, no failerequest tracing logs./
except that process in worker process tab unable to find anything.
tried resting app-pool,iisreset and changing managed pipeline mode from integrated to classic but still no luck.

Thanks

Hi MeSrp-5701 Usually we need to troubleshoot based on the error message, but you have no related error messages in the event viewer, logs, and frt, so it is impossible to determine the problem.

Thanks,
Issue resolved after server restart, but I'm unable to find any RCA.
I think we can mark this as closed.
