>Release: FreeBSD 2.2.8-STABLE i386
>Organization:
Barry Lustig & Associates, Inc.
>Environment:
System is acting as a ypserver in a mixed environment of Solaris, IRIX, AIX, and FreeBSD systems.
>Description:
ypserv is continually core dumping with a segmentation violation. xprt is
NULL. I've added the code from current to check whether xprt is NULL, but
am still running into segv's at the same point.
dns5(14)# gdb /usr/sbin/ypserv-d /ypserv-d.core
Core was generated by `ypserv-d'.
Program terminated with signal 11, Segmentation fault.
