Hi,

I have just upgraded my machine from FreeBSD-6.1-PRERELEASE to 
FreeBSD-7.0-CURRENT.

gw# uname -an
FreeBSD gw.micom.mng.net 7.0-CURRENT FreeBSD 7.0-CURRENT #0: Tue Mar 21 
09:00:50 ULAT 2006 tsgan@gw.micom.mng.net:/usr/obj/usr/src/sys/GW  i386

When I restarted the machine right after mergemaster, it said following 
error and
didn't run rc scripts. I had to manually start some scripts.

...
pid 104(rcorder), uid0: exited on signal 11 (core dumped)
Segmentation fault (core dumped)
