                 Key: HBASE-4278
                 URL: https://issues.apache.org/jira/browse/HBASE-4278
             Project: HBase
          Issue Type: Sub-task
            Reporter: Li Pi
            Assignee: Li Pi


Just a race condition in 4027. Occurs due to a spinlock that happens if the slab allocator
is empty. When the slab allocator gets gets a slice of memory returned, if multiple threads
are locked, both can be freed at the same time, leading one to throw an exception.
