Didn't get the message through the list for some reason - replying
indirectly.
When FarmSize is set, the workers message via Gossip backend (currently
Redis) about reachability of the next hop. By default all workers use
Status-Server probes. However, it's likely that this probing is
excessive, so you should try something like this:
# see goodies/farmsize.cfg for a full example
<Gossip>
# Parameters
</Gossip>
<AuthBy RADIUS,RADSEC,HASHBALANCE,etc.>
Gossip
UseStatusServerForFailureDetect
KeepaliveTimeout 5
NoKeepaliveTimeoutForChildInstances
# Other parameters
</AuthBy>
To summarise: with the above one worker (instance #1) does the probing
and uses Redis to keep the other workers informed about the next hop
reachability.
Thanks,
Heikki
