            Bug ID: 1179663
           Summary: CIFS:[USS]: glusterfsd OOM killed when 255 snapshots
                    were browsed at CIFS mount and Control+C is issued
           Product: GlusterFS
           Version: mainline
         Component: snapshot
          Keywords: ZStream
          Severity: high

+++ This bug was initially created as a clone of Bug #1178620 +++

Description of problem:
glusterfsd OOM killed while browsing the .snaps from CIFS mount, Control+C was
issued. 

Version-Release number of selected component (if applicable):

How reproducible:
100%

Steps to Reproduce:
1. Create a 2*2 volume and start it
2. mount the volume and copy the /etc to the CIFS mount point
3. Enable USS 
4. Take 255 snapshots on the volume
5. cd .snaps at the CIFS mount
6. Do ls -al and control+C 

Actual results:
The .snaps contents are not shown properly and it says .snaps/<snap-dir>/xx.yy
is not a directory and the snapd port got closed. There is a glusterfsd OOM
kill as well.

Expected results:
There should not be an OOM kill issue and the control+C event should be handled
gracefully.
