--- Comment #9 from Raghavendra G <rgowdapp at redhat.com> ---
Continuing with my tests. I do see changelog creating a listener socket for
each brick. Following are the results on a server process with 1000 bricks
multiplexed

[root at unused glusterfs]# ps ax | grep -i testvol
16512 ?        Ssl    2:33 /usr/local/sbin/glusterfsd -s booradley --volfile-id
