Subject CompactionExecutor holds 8000+ SSTableReader 6G+ memory
Date Wed, 26 Jun 2013 05:13:51 GMT
I have 4 nodes cassandra cluster. Every node has 32G memory, and the
cassandra jvm uses 8G. The cluster is suffering from gc. Looks like
CompactionExecutor thread holds too many SSTableReader. See the attachement.

Why ?
