nothing conclusive:
(gdb) kvm proc (0t3419384356 & ~15)
#0  0xcbd756e0 in ?? ()
(gdb) bt
#0  0xcbd756e0 in ?? ()
#1  0x00007020 in ?? ()
#2  0xcbd756e0 in ?? ()
#3  0x00000000 in ?? ()

However, I can get the name of the lwp anyway:
print *(struct lwp *)0xCBCFAA20
  l_name = 0xcba63aa4 "slave",

which was created by nfsd:
% grep -r slave src/usr.sbin/nfsd/
src/usr.sbin/nfsd/nfsd.c: pthread_setname_np(pthread_self(), "slave", NULL);

Also, nfsd was launched by the following command also:
#nfsd -t -u -n 6

 - Arnaud

ps: I can provide you the core and the debugging image if you want, it
might be easier that proxying command :)
