            Bug ID: 1358608
           Summary: Memory leak observed with upcall polling
           Product: GlusterFS
           Version: mainline
         Component: upcall
          Severity: high
          Assignee: bugs at gluster.org
          Reporter: skoduri at redhat.com

Description of problem:

There is memory leak observed when there are large number of upcall
notifications generated. Ideally after polling them, all the upcall events
generated should be cleaned up. But that wasn't the case. There were few upcall
events not cleaned up and resulted in memory leak.

The issue is that during polling (currently), upcall entries are not removed
under mutex lock. This resulted in the list corruption leaving few entries from
being removed.
