Tentacle Exception

We are getting the following tentacle exception on all of our servers every 10 seconds. Can we do something to make this stop or is there a known bug for this? We are running the latest tentacle version.

Hi Dan,

This frequently occurs when another Octopus server, e.g. a 1.6 machine, is still trying to connect to the (new) Tentacles. Could that be the case here?

Regards,
Nick
