xpaulbettsx/SassAndCoffee — Issue #50: Intermittent IndexOutOfRangeException causing 100% cpu
Author: dizzib

State: open

My server event log shows the following error after a request causes the cpu to peg at 100% requiring a kill of w3wp.exe, at which point a new w3wp.exe starts and the request completes.

Running v2.0 with file cache enabled and output cache disabled.

I've logged it here as a separate issue to aid with tracking. Hope that's ok.

Cheers!
Andy.
