             Summary: Disk space growth until restart
                 Key: CASSANDRA-7042
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7042
             Project: Cassandra
          Issue Type: Bug
         Environment: Ubuntu 12.04
Sun Java 7
Cassandra 2.0.6

            Reporter: Zach Aller
            Priority: Critical


Cassandra will constantly eat disk space not sure whats causing it the only thing that seems to fix it is a restart of cassandra this happens about every 3-5 hrs we will grow from about 350GB to 650GB with no end in site. Once we restart cassandra it usually all clears itself up and disks return to normal for a while then something triggers its and starts climbing again. Sometimes when we restart compactions pending skyrocket and if we restart a second time the compactions pending drop off back to a normal level. One other thing to note is the space is not free'd until cassandra starts back up and not when shutdown.

I will get a clean log of before and after restarting next time it happens and post it.

Here is a common ERROR in our logs that might be related
