Hi @Tevon2.0 ,
Please try below for troubleshooting Event ID 6398 and "The Execute method of job definition Microsoft.Office.Server. UserProfiles .FeedCacheRepopulationJob threw an exception" issue.
- Go to Central Administration->Application Management->Manage services on server->select your search server in Server section located in the top-right corner. Check if there is Distributed cache service, if so, stop it.
- Try to increase the timeout for the LMTCache and DistributedActivityFeedCache using PowerShell command below:
$lmtcache = Get-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedLMTCache $lmtcache.RequestTimeout="10000"
Set-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedLMTCache $lmtcache
$feedcache = get-SPDistributedCacheClientSetting -containertype DistributedActivityFeedCache $feedcache.RequestTimeout="10000"
Set-SPDistributedCacheClientSetting -ContainerType DistributedActivityFeedCache $feedcache
Then use the following command to populate the cache quickly:
Update-SPRepopulateMicroblogLMTCache -ProfileServiceApplicationProxy <SPServiceApplicationProxyPipeBind> [-AssignmentCollection <SPAssignmentCollection>]
Update-SPRepopulateMicroblogFeedCache -[AccountName <AccountName>] -ProfileServiceApplicationProxy <SPServiceApplicationProxyPipeBind> [-AssignmentCollection <SPAssignmentCollection>] [-SiteSubscription <SPSiteSubscriptionPipeBind>]-[SiteUrl <SiteURL>]
Reference: User Profile Server Application - Jobs fail
- Check the ULS log for more detailed information. If there is any error message in the ULS log related to "No DNS entries exist for…", if so, verify that the DNS does not in fact exist and then add the appropriate DNS entry for the server. Reference: The Execute method of job definition Microsoft.Office.Server. UserProfiles .FeedCacheRepopulationJob threw an exception If the issue exists, try to remove and re-add the Distributed Cache Service:
Stop-SPDistributedCacheServiceInstance
Remove-SPDistributedCacheServiceInstance
Add-SPDistributedCacheServiceInstance
