Hi

Running a multi-site on Umbraco version 7.15.3 assembly: 1.0.7180.24662 2 websites, with the same structure, different designs.

The application pool keeps stopping and the Examine indexes seem to get corrupted or we have an error that they cannot be written to?

This brings both websites down, it's happening multiple times a day, sometimes multiple times per hour, which I can only think is when more traffic is using the site.

The error logs on the server read:

An unhandled exception occurred and the process was terminated

Application ID: /LM/W3SVC/44/ROOT

Process ID: 41844

Exception: System.IO.IOException

Message: Cannot overwrite
