We're seeing the message referenced in the subject sometimes thousands of times per day per node and we believe it's impacting performance. I haven't really found a pattern - different nodes, different queries (though seems more common with INSERT...SELECT that triggers a mergeout). Customer is on 8.1.1-9. Related support case is SD02239275. Sample below but can provide GB's of logs as needed. Thanks!
