--- Comment #4 from Milind Changire <mchangir at redhat.com> ---
Glad to hear things are working for you.

My hypothesis is that glusterd starting a large number of bricks causes a
flood/rush of brick process to attempt to connect back to glusterd. This causes
SYN Flooding and eventually drop of connection requests causing loss of service
due to insufficient resources for holding connection requests until they are
acknowledged. Hence the reference to tweak the glusterd vol file option:
transport.listen-backlog.

You could take a look at /var/log/messages and "grep -i" for "SYN Flooding" and
see if that's the case. 

If things are working for you, you could close this BZ as WORKSFORME.
