An unhandled exception occurred and the process was terminated. Application ID: /LM/W3SVC/1439897242/Root Process ID: 61836 Exception: System.NullReferenceException Message: Object reference not set to an instance of an object. StackTrace: at Lucene.Net.Store.FSIndexOutput.Finalize()
6 seconds later the very next error (as a result of the first one)
this looks like some lucene-related code is executed in a different thread... and if there's an unhandled exception in another thread it KILLS the worker process, which is.... bad... bad... bad...
The solution seems to be (quoted from the other thread)
"I had the same problem but with V4. I was unable to guess what might be wrong and I was reluctant to reinstall a third time.
The DW20.EXE process gets kicked off and it basically killed my site. If you search the web for DW20.exe you may be mislead into thinking it's Dr Watson. It isn't. It's the error reporting service. You need to disable it
Start Menu/SSettings/Control panel/System/Advanced/Error Reporting and check the disable option but leave on the "Notify when critical errors occur" option.
Then, when you next cause the error you can debug it because you are not getting slammed by DW20.EXE.
In my case it was an access right to Umbraco.Config.
