I was about to respond to say that repair doesn't fail just due to failure detection, but this appears to have been broken by CASSANDRA-2433 :( Unless there is a subtle bug the exception you're seeing should be indicative that it really was considered Down by the node. You might grep the log for references ot the node in question (UP or DOWN) to confirm. The question is why though. I would check if the node has maybe automatically restarted, or went into full GC, etc. -- / Peter Schuller (@scode, http://worldmodscode.wordpress.com)
