On sid, ipv6 is compiled in to the kernel so it can only be disabled
via "ipv6.disable=1" on the "linux" line in "grub.cfg".
If you've compiled your own kernel with ipv6 as a module, have you
tried disabling ipv6 with "install ipv6 /bin/true" in
"/etc/modprobe.d/ipv6.conf" and rebuilt the initrd after running
"depmod -a"?
Is "cat /proc/sys/net/ipv6/bindv6only" the same on working and
non-working nodes? This setting restricts the ipv6 socket to ipv6 (or
not) and had created problems in the past for some apps.
