After discussing with Ralph, he pointed out we should activate the
distributed_lock as we have multiples processes querying the same memcached
servers. In addition, Ralph suggested that we use both memcached01 and
memcached02 servers instead of relying on one only.
The diff on the pkgdb2 config becomes:
diff --git a/ roles/pkgdb2/templates/pkgdb2.cfg b/ roles/pkgdb2/templates/pkgdb2.cfg
index 828d41d..cd8e862 100644
