> URL: https://issues.apache.org/jira/browse/CASSANDRA-1188
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7
> Environment: Ubuntu 10.04

> Insert 1000 rows into a super column family. Read them back in a loop using multiget_slice. Note leaked file descriptors with lsof:
> lsof -p `ps ax | grep [C]assandraDaemon | awk '{print $1}'` | awk '{print $9}' | sort | uniq -c | sort -n | tail -n 5
> Looks like SSTableNamesIterator is never closing the files it creates via the sstable ...?
> This is similar to CASSANDRA-1178 except for use of multiget_slice instead of get_slice
