I've upgrade a kernel on my server (i386) from 4.99.20 (around June 20)
to yesterday's 4.99.25, but after that ypserv(8) (both old 4.99.20
and new 4.99.25 binaries) seems to stop working.

ypserv(8) is started via rc.d(8) normally, but it doesn't
respond any requests from ypbind(8) even from localhost.
ypserv -l (logging requests) option just says
"domain_nonack_2: request from localhost, domain foo, served TRUE"

Does anyone see the similar problem?
