We have been experiencing intermittent problems for users that access SharePoint 2013. Sometimes the images are distorted and other times some sites do not render. Error 'something went wrong' appears with a correlation ID. Recently I had to perform iisreset which did not restore normal functionality, then re-booted server which worked. I need to find a fix before the problem repeats itself. (its been ongoing before I took the job on)
I've tracked this down in the events and the error points to the distributed cache I think. Is there anything else I should be checking for?

The current version of AppFabric that's installed on the wfe and App server is v1.1 (1.1.2106.32), CU1
We are running 1 WFE and 1 APP server.
Under windows services > WFE > AppFabric Caching Service - set to Automatic and on App Server it is disabled.
SharePoint > Services on Server >WFE >Distributed Cache - Started SharePoint > Services on Server >APP >Distributed Cache is not listed
The link below lists CU with latest being CU7. I wanted to confirm which CU I should be looking at installing?

Can I install the AppFabric CU before SharePoint CU's or is the Appfabric CU already included in one of the SharePoint CU's?
