My 7.0-CURRENT box got a strange error message during shutdown process since some time. Don't know exactly when it started. See the following for details. # uname -a FreeBSD 7.0-CURRENT FreeBSD 7.0-CURRENT #4: Wed Aug 17 15:51:06 CEST 2005 acex5@:/usr/obj/usr/src/sys/GENERIC sparc64 # init 0 Shutting down daemon processes:.

Maybe something went wrong in code cleanup of file src/sys/netinet6/udp6_usrreq.c three weeks ago. Best Regards, Sebastian
