6to4 IPv6 problems FreeBSD 6.2 p4

[Ofloo]

Jun 22 15:46:45 spark kernel: Jun 22 15:46:45 spark sshd[69427]: error:
ssh_msg_send: write

The system is up for 3 days now and hasn't crashed like it did daily since
the last 20 days, now all i changed was not connecting to ssh using IPv6 so
I searched my logs, and I found the error above, could this cause the
computer to crash !? And if so what can I do about it, .. sshd shouldn't
crash when a I login through an IPv6 client, .. or has it still experimental
IPv6 support !?
