Hi tiny3001,

start troubleshooting why the queues are blocked. See the wiki http://wiki.splunk.com/Community:TroubleshootingBlockedQueues or use the S.o.S. App https://apps.splunk.com/app/748/ on the indexer. As well start to setup persistent queues on the UF http://docs.splunk.com/Documentation/Splunk/6.2.0/Data/Usepersistentqueues

cheers, MuS
