This is causing the heavy traffic at the KDC, plus intermittent "Requ= est is a replay" (which indicates race condition at KDC while handing out t= he TGT for the same principal). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@lucene.apache.org For additional commands, e-mail: dev-help@lucene.apache.org
