Anton Winter commented on CASSANDRA-4321:
-----------------------------------------
After working around the issue with the 0003 v5 patch that Omid refers I've had
an sstablescrub complete on one of my servers. sstablescrub did detected
several overlapping sstables, resetting them to L0, but no out of order keys.
The Last written key DecoratedKey >= current key exception however resurfaces
again after the first set of compactions, 5 minutes after startup, in the exact
same manner as before. The same exception occurs for various CF's until
compactions stop completely. compactionstats still shows a large number of
pending compaction tasks after this event.

> After upgrading to 1.1.1 (from 1.1.0) I have started experiencing
> StackOverflowError's resulting in compaction backlog and failure to restart.
> The ring currently consists of 6 DC's and 22 nodes using LCS & compression.
> This issue was first noted on 2 nodes in one DC and then appears to have
> spread to various other nodes in the other DC's.
> When the first occurrence of this was found I restarted the instance but it
> failed to start so I cleared its data and treated it as a replacement node
> for the token it was previously responsible for. This node successfully
> streamed all the relevant data back but failed again a number of hours later
> with the same StackOverflowError and again was unable to restart.
> The initial stack overflow error on a running instance looks like this:
