If you are using the GENERIC NetBSD/sun3x-1.3 kernel, then the error you
have described above is occuring inside the function copyinstr().
Luckily, the GENERIC kernel is compiled with DDB (the debugger.)  It would
help if you could type ``trace'' at the db> prompt the next time this
happens.  Then send us the result.
