That sounds like something wrong with the way the rows are merged during
compaction then.
Can you run the compaction with DEBUG logging and raise a ticket? You may want
to do this with the node not in the ring. Five minutes after it starts it will
run pending compactions, so if there if
snapshot all nodes so you have a backup: nodetool snapshot -t corrupt
run nodetool scrub on the errant CF.
Look for messages such as:
Out of order row detected…
%d out of order rows found while scrubbing %s; Those have been written (in
order) to a new sstable (%s)
In the logs.

Aaron,
thanks for your help.
I ran 'nodetool scrub' and it finished after a couple of hours. But there
are no infos about
out of order rows in the logs and the compaction on the column family still
raises the same
exception.
With the row key I could identify some of the errant SSTables and
Hi,
I'm running a 6 node Cassandra 1.1.5 cluster on EC2. We have switched to
leveled compaction a couple of weeks ago,
this has been successful. Some days ago 3 of the nodes start to log the
following exception during compaction of
a particular column family:
ERROR [CompactionExecutor:726]
