When the Analytics Event Router stops moving data for a long period of time the JMS queue can stop functioning correctly.  Then Oracle Knowledge instances will receive errors.

First check the instance logs to see if the instances can reach the JMS queue or if this is an Analytics event router issue.

If the server stops running then some events are lost.  Some events can be recovered with the help of Oracle support.
