Ravi Prasad commented on CASSANDRA-6716:
----------------------------------------
Do you see the missing file(s) compacted before in the logs ? I've been seeing
ocassional FileNotFoundException during compaction running 2.0.5, but not able
to reproduce consistently. in our case, the missing file was compacted away,
but for some reason they weren't cleaned up, and after restart, looked like the
sstable was loaded opening a reference before getting cleaned up by
cleanupCompactionleftovers. the issue goes away after another restart for me.
Could be related to CASSANDRA-5151 and CASSANDRA-6086.

> It seems that since recently I have started getting a number of exceptions
