It seems rather fiddly to debug IMO. Basically, one watches the z3950* tables and the daemon's logfile and see what it's saying as a query is submitted.

Even so, I still had one of my client libraries banned from a z3950 server following undetected problems and repeated requests that were more-or-less a denial of service attack.

Being banned from a Z39.50 server could be a very serious problem. I have often wondered about the risks entailed in establishing permanent connections to a Z39.50 server when the process might run unattended. One does not want the query to fail before it is finished fetching the records, however. A user settable timeout function as a fail safe might avoid some risks of an unattended process. One would want to close a Z39.50 connection that had run for too long a time or stop and restart the Z39.50 daemon if a connection had been open too long.
