Subject [jira] [Created] (CASSANDRA-10864) Dropped mutations high until cluster restart
Date Mon, 14 Dec 2015 21:28:46 GMT
Jeff Ferland created CASSANDRA-10864:
----------------------------------------

             Summary: Dropped mutations high until cluster restart
                 Key: CASSANDRA-10864
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10864
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jeff Ferland


Originally raised and investigated in https://www.mail-archive.com/user@cassandra.apache.org/msg44586.html

Cause is still unclear, but a rolling restart has on two occasions since been performed to
cope with dropped mutations and timed-out reads.

Pattern is indicative of some kind of code quality issue possibly involving locking operations.
Stack flame graphs do not show a clear difference between restarts.
