Omid Aladini commented on CASSANDRA-4411:
-----------------------------------------
I can confirm that the problem is still there. I offline-scrubbed using 1.1.3
(sstables were generated by 1.1.0) , but the scrubber did not report any
out-of-order sstables, but sent some sstables back to L0. On compaction though,
I get the exception:

> As instructed in CASSANDRA-4321 I have raised this issue as a continuation of
> that issue as it appears the problem still exists.
> I have repeatedly run sstablescrub across all my nodes after the 1.1.2
> upgrade until sstablescrub shows no errors. The exceptions described in
> CASSANDRA-4321 do not occur as frequently now but the integrity check still
> throws exceptions on a number of nodes. Once those exceptions occur
> compactionstats shows a large number of pending tasks with no progression
> afterwards.
