rc just stops..)

Output from 'portmap -v -d' :

Lastcomm says that the system is filled with portmappers...

(dirac (2.2.7-RELEASE) runs ypserv...)
I think its a ypbind problem (but I might be totally wrong...)
I have logs available: tcpdump syslog lastcomm
I've seen something like this on 2.2.7-RELEASE (dirac) some time ago,
but only once, so I can't supply any logs...
>How-To-Repeat:
Just boot many many times :-)
>Fix:
Unknown! (I don't see trough ypbind.c...)
