If you have a heterogeneous network like I have then host byte ordering
could be the problem. Make sure

1	you define NETWORK_DATABASE in your NN configuration (config.h)
2	do NOT define NETWORK_BYTE_ORDER in conf/m-whatever.h if your
	architecture is not already network byte order (little-endian?)
3	Define the functions htonl() and ntohl() if necessary in the
	conf/m-whatever.h file above
3	rebuild the database if necessary.

I had this problem trying to share the NN database between Kralizec, a Sun
3/60 and Godzilla, a Linux box. The NN 6.4.18 shipped with Linux SLS was
configured for host byte order. I had to modify conf/m-i80386.h because
the file was written to invoke compiler errors.

Hope this helps, Nick.
