Steven Hawkins updated TEIID-1986:
----------------------------------
Fix Version/s: (was: 8.0)
Affects Version/s: 7.7
(was: 8.0)
I recall seeing this before, but didn't delve into it at the time. So this is when a load is needed, but it's not blocking so we perform it in the background. Everything piggy-backs off of the user requests so that we don't require some kind of system account to do materialization. Why are we looking back up the original request? We could either not dispose of the request even if it is closed until pending asynch operations have completed or spawn a full request to represent asynch loads.

> I am consistently seeing the below exception, when the slave node trying to refresh the cache. After the failed attempt the cache seems to be getting TTL refreshed, so it keeps serving the old results until the cache time expires again. Next time it loads fine.
