Event ID 6398 – Unexpected exception in FeedCacheService.ISRepopulationNeeded

So I recently went crawling through some event logs while doing a health check on a SharePoint farm. I noticed this one in particular so I thought I’d investigate further.

The Feed cache service depends on the Distributed Cache Service, so checking if the distributed cache service is running in Central Administration (manage services on server section) is the first step. Tags and document activities are saved only to the Feed Cache, they are not persisted to content databases, so if the distributed cache service is stopped, the tags and document activities are lost. If the Distributed Cache service is started, repopulation occurs when the feed cache repopulation timer job runs every 5 minutes.

So with the information above, I checked the timer jobs that relate to this as well as the service in CA, both were setup correctly. The next step was to look into PowerShell to find out if the Cache host was working to which I found out it wasn’t.

Following the error shown above I thought I’d try and connect to the App Fabric Cluster Configuration and then restart it which thankfully worked.

Running Get-CacheHost again after the restart is complete will show you the Cache Host values.

Either run the timer job manually or wait 5 minutes for it to run then check the event viewer, hopefully the issue is gone!

There are other fixes out there for this however, this is the fix that seemed to work for my environment.
