Azure Web Application Crashing 10 to 30 minutes + App Pool Recycles


I am seeing these errors in "Application Crashes"

88 crashes due to (0xC0000005 - Native Access Violation), 4 crashes due to (0xE0434352 - CLR Exception)

App Service is running on S3 app service plan. Memory and CPU don't seem to be an issue.

Doesn't seem to be consistent, seems to crash every 20 to 30 minutes but can sometimes be quicker. Always On is enabled.

There isn't alot to go on here but would suggest the following to try and narrow down...

  • Make sure any 3rd party libs you're using are supported on the version of .NET in the app service.

  • Enable diagnostic logs to get additional details on the fail to see if the problem area can be narrowed down

  • Enable app insights to help narrow down

  • If the above doesn't help, you could try and recreate the issue locally so you can debug as described here
