What version of NetBSD, and what error do you get?
For me this works fine on 2.1/i386 (actually, I don't know from what OS 
version the crashdumps are, might be old):

 	noon# cd /var/crash/
 	noon# ls
 	bounds              netbsd.0            netbsd.1.core.gz    netbsd.3.core.gz
 	minfree             netbsd.0.core       netbsd.2.core.gz

No idea - I guess there's a panic message that tells you.
Or what do you mean by "crash"? Normal ftpd.core?
