We have an application page that stores some information in the view state, and uses UpdatePanels. We have a rare, intermittent bug that occurs in SharePoint 2013 only whereby sometimes, after a button click (that should trigger a partial refresh via an UpdatePanel), the page goes back to it's blank state.
I finally caught this with an interesting ULS log:
Unexpected error occurred in method 'GetObject' , usage 'SPViewStateCache' - Exception 'Microsoft.ApplicationServer.Caching.DataCacheException: ErrorCode<ERRCA0018>:SubStatus<ES0001>:The request timed out.
I was able to reproduce the bug once by stopping/starting the distributed cache service while working with the page (however, I couldn't do it consistently).
So, first of all, is this likely the culprit, and second, is it possible to disable the ViewStateCache for a particular page?
This is an admin page that only a few people would even have access to, and I don't think caching is helping anything at the best of times.
