My server application event logs are showing the following errors which appear to occur intermittently and usually after a period of inactivity. In each case, immediately resubmitting the same request then works without error.
Running v2.0 with file cache enabled and output cache disabled.
Exception information:
Exception type: IndexOutOfRangeException
Exception message: Index was outside the bounds of the array.
