Description
Cassandra 1.2.11
When trying to snapshot, I encountered this error. It appears that snapshot doesn't lock the sstable list in a keyspace which can cause a race condition with compaction. (I think it's compaction, at least)
[cassandra@dev-cass00 ~]$ cas cluster snap pre-1.2.12

Nodetool command "snapshot -t pre-1.2.12" failed!
Output:
Requested creating snapshot for: all keyspaces
