             Summary:  Backup segments may not be removed after failed state transfer
                 Key: ISPN-5268
                 URL: https://issues.jboss.org/browse/ISPN-5268
             Project: Infinispan
          Issue Type: Bug
          Components: Core
            Reporter: Tristan Tarrant
            Assignee: Dan Berindei


Dist cache can lost data if the primary and all backups are lost at the same time.  To detect such data loss, they are monitoring the tatal sum of entries from all nodes using JMX.  If the sum reduces by a considerable ammount, data loss (by lost a segment) is concluded.  But they found a case that the sum increases, not decreases, after failed state transfer.  This is probably caused by an extra backup segment that hasn't been cleaned up when the last state transfer failed.
