Omid Aladini commented on CASSANDRA-4321:
-----------------------------------------
Tried v4 patch and offline scrub went through completely. Cassandra started
without any error but compaction halted again:

All SSTables that participated in compaction were new ones written by the
offline scrub (according their timestamp and also id range.) although the first
one didn't exist any more (already promoted before the exception?)
{quote}This is not really a new bug, but I believe that prior to
CASSANDRA-4142, *this had less consequences*.{quote}
Sylvain, could you please elaborate on this? I'd like to know how pre-1.1.1
data is affected by the Range-vs-Bounds bug. Only overlapping/duplicate
sstables on the same level leading to slower reads caused by unneeded sstable
lookups?

> 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:
