Unfortunately that doesn't give any information.  You'll need to
recompile rpc.lockd with GDB debugging symbols (add -ggdb to CFLAGS).
See the developer's handbook on the website for more information about
debugging program failures with gdb (specifically, how to obtain a
useful backtrace).

Well, I recompiled rpc.lockd using -ggdb and -g, but when I launch the following command:
$ gdb /usr/sbin/rpc.lockd
... I get:

GNU gdb 5.2.1 (FreeBSD)

This GDB was configured as "i386-unknown-freebsd"...(no debugging symbols found)...

How come no debugging symbols are found ?

Here is how I compiled rpc.lockd
( CFLAGS= -g -ggdb -O -pipe ):
$ rm -Rf /usr/obj/*
$ cd /usr/src/usr.sbin/rpc.lockd
$ make clean && make obj && make depend && make all install

rm -f nlm_prot_svc.c nlm_prot.h test rpc.lockd kern.o nlm_prot_svc.o lockd.o lock_proc.o lockd_lock.o rpc.lockd.8.gz
/usr/obj/usr/src/usr.sbin/rpc.lockd created for /usr/src/usr.sbin/rpc.lockd
rpcgen -L -C -m -o nlm_prot_svc.c /usr/include/rpcsvc/nlm_prot.x
rm -f .depend

install -s uses strip(1), so all your debugging symbols are erased. the original binary left in-place should have debugging symbols.
