With adequate replication traffic that is delayed or just slow, you can have a batch of 64MB of updates to a Region which are all on a different RegionServer by the time the RS processes it.
In a run of IntegrationTestReplication that is particularly "slow"/oversaturated, I saw 1.591M log lines taken up with this message out of a total number of line of 1.597M lines (99.6% of the log). I propose that after the first WrongRegionException we see in {{doMiniBatchMutation}}, we stop printing out the rest of the stacktrace (save on 13 lines for every occurrence).
