Description of problem:

I was executing a script for related to quota test. The script is about creating 10000 directories and creating data in them after setting limit on the directories.

Meanwhile this test was going, executed 
gluster volume quota $VOLNAME list

NOTE: script kept running overnight, and the above mentioned list command was executed in the morning.

and seems the glusterd crashed.

How reproducible:

Steps to Reproduce:
1. execute "gluster volume quota $VOLNAME list", while gluster command may be used for setting limit on directories.
