postfix/master broken in -current?

[Markus W Kilbinger <mk%kilbi.de@localhost>]

Hi!

After upgrading my qube 2 to actual -current kernel and userland
(cross compiled from scratch on my amd64 machine) I see postfix/master
failing repeatedly mostly after processing/delivering some mails
successfully (ktrace output):

Working kernel und userland was about 2 weeks old. No (postfix) config
changed.

Any ideas? More info I can provide?
Does anybody else see this?
