--- Comment #4 from Atin Mukherjee <amukherj at redhat.com> ---
Found another race where glusterd was restarted glusterd_brick_start () is
called multiple times due to friend handshaking and in one instance when one of
the brick was attempted to be attached to the existing brick process,
send_attach_req failed as the first brick itself was still not up and then we
did a synlock_unlock ( )followed by a sleep of 1 sec, before the same thread
woke up, another thread tried to start the same brick process and then it
assumed that it has to start a fresh brick process.
