Paul,

 Thanks a lot for the excellent report, and sorry for not being
reactive at this time.

 I suspect you get different results because of timers. Carob features
pinger threads and timeouts to decide when a controller or a VDB is
available. So availability status may depend on the moment. This is
just a piece of explanation; not an excuse for the behaviour you are
experiencing, which is not normal.


Do you have some kind of firewalling between the client and the
controllers? If you block the pings, all kind of weird behaviours may
happen.

Cheers,

Marc.
