I've seen this before and it wasn't a tftp problem, per se, rather a
default limit in the number of connections inetd (or xinetd) will
allow you to open in a set amount of time (I think its connections per
minute?). Once it reaches that limit it disables the service
temporarily to prevent DoS attacks.

You can bump up this limit in the xinetd/inetd config files.

That's assuming, of course, that  you're not running a standalone tftp
server.
