I've timed the freezes and it works out to be 2 seconds every time. So
token loss looks like a likely candidate.
We have a peculiar setup where all the machines appear to be on a single
virtual LAN but we observed this behaviour before we separated the two
ends. So I'd like do a test where I put each machine in its own segment
and see whether . Is is possible to set up a spread.conf where machines
on the same subnet are in separate segments?

This is what I would have expected. But we seem to only see problems in
The other oddity is that adding messages into the mix seems to remove
the problem. But what we may be doing there is influencing the token
