RavenDB error on Index Save

[Michael Carter]

Just started getting these errors. RavenDB v2.5.2910

Error occurs when adding/changing indexes on first launch via IndexCreation.CreateIndexes() as well as adding/changing indexes via Raven Studio.

I looked in the CompiledIndexCache folder and see the C# class that is generated, but apparently when Raven tries to compile to an Assembly, csc.exe is crashing.

I haven't made any configuration changes on the server. I've tried restarting RavenDB (it's running as a Windows Service). I haven't tried rebooting (hope it doesn't come to that).

Anyone else see this issue?

Thanks!

Can you check if your user service has permissions to write to that directory?

Also, do you have any process (AV, Indexing) that might touch this file?

I ended up rebooting the server and it looks like the error went away.

I'll post again if it happens again.

Thanks!
