Reading this message and your original report, I can't seem to determine 
under exactly what conditions this problem is supposed to occur.  Does the 
problem occur with

- amd64 clients talking to amd64 servers?
- amd64 clients talking to i386 servers?
- i386 clients talking to amd64 servers?
- Some other combination?

In each case, exactly what OpenAFS versions are the client and server?
If the fileserver crashes, does it leave a core file behind?
If so, run gdb on that fileserver binary and core file, type 'where', and 
send the results.
