I've fixed it:

This is a ringtest between two different Linux machines and two
Solaris hosts (both x86) in a mixed environment.

The two Linux nodes talk via RFC1918 (192.168.1.x) - the fastest connection
between them. One of them talk to the Solaris via public IPv4 (141.x.y.z),
also the fastest connection, the other Linux system (which is 192.168.1.131
and doesn't have a public IPv4 address) uses IPv6 to communicate
with the second Solaris, because no faster (other) connection is
available. (it's a node from the formerly RFC1918-only cluster which
now has its own IPv6 subnet (2001:638:908:1/64))

Things are getting interesting... ;)
