Hi all--

had a crash today on a machine on which we do a lot of file access via 
samba.  it is running 2.0.2 vanilla/generic:
NetBSD 2.0.2 (INSTALL) #0: Wed Mar 23 09:13:49 UTC 2005
jmc@faith.netbsd.org:/home/builds/ab/netbsd-2-0-2-RELEASE/i386/200503220
140Z-obj/home/builds/ab/netbsd-2-0-2-RELEASE/src/sys/arch/i386/compile/INSTALL


was able to get this out of the db prompt:

I have no problem upgrading to something like 2.1 but is there a way to 
find if a problem like the above has been addressed?  thanks!
