Hi Rob, We do not currently run repairs because we know our deployment time for each cassandra node is very short. I do understand we have to run repairs but would repair be in the picture here when no nodes in the cluster were down for last 2 weeks?

We have seen this in Prod 3 times in last 1 week and coincidentally all 3 times on the same partition. We have confirmed that nodes didn't go down (they were all started on Oct 28). I do not see any resource issues (CPU is around 5%, memory < 10%, iostats looks normal etc) on any nodes. Do you run repair once every gc_grace_seconds? =Rob
