------------------------------------------------------
Key: CASSANDRA-1300
URL: https://issues.apache.org/jira/browse/CASSANDRA-1300
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.6.3
Reporter: Anthony Molinaro
I have a set of 4 sstables which equal about 600GB of data, whenever they are
compacted after about 2 days I get this exception
ERROR [COMPACTION-POOL:1] 2010-07-17 19:09:49,784 CassandraDaemon.java (line

After this expection, the compaction starts over and then crashes again. This
led to several thousand outstanding sstables hanging out waiting to be
compacted.
