This might be related to a fix, that needs testing, with respect to
the mbuf data size.  The thing I'm thinking about is this:

There are reports that racoon is unable to complete IKE negotiation
due to a send to the pfkey socket returning ENOBUFS. This appears to
be a result of an incorrect assumption about mbuf data size due to a
change resulting from mbuma. A fix for this is in RELENG_5 now.


You might want to update your system.

=46rom what you say in your email this looks like an intermittent
error. Have you been able to reproduce this?

Thanks,
George
