[PATCH] Avoid using CTDB_BROADCAST_ALL (bug 13056)

[Amitay Isaacs]

Hi,

CTDB in some places uses CTDB_BROADCAST_ALL to
distribute packets to all the configured nodes.  If there is a
dead node (or a node that is not running) in the cluster,
then ctdb daemons will queue up packets for such nodes.
Over long periods of time, ctdb daemon can consume lots
of memory which will not be freed till the dead node is
started or ctdb daemon is restarted.

Use CTDB_BROADCAST_CONNECTED instead to send
packets to the nodes that are running.

Please review and push.

Amitay.
