I've been having some troubles with a specific host trying to join my spread network.  Here is the log for my latest attempt... The Spread 'cluster' has been up and running for several weeks no problems.
[Fri 03 Dec 2010 14:14:12] Net_ucast_token: Token too long for packet!
At which point the Spread daemon was no longer running :(  Other daemons in the group/segment seemed to start having messages out of order and everything went a bit weird.
I had originally tried to run a spread daemon on the server but that totally breaks all other daemons, with a massively increasing "s retrans" count.  The whole network grinds to a halt as that number goes up (and we hit > 90Mbit/sec!)  I don't believe there is a networking problem, but the "s retrans" issue would suggest there is.  I've confirmed and it's not a firewall issue, another host on the same LAN (next switch port along) is absolutely line.  All are running FreeBSD and all have been patched for the size_t 64 bit problem.
Anybody have any idea where to look as I really need to get this machine in the loop!
