for the mbuf allocator i did these rate-limited (once per second).
Maybe you could do the same there. Something like this:
if ( <error condition> ) {
static int last_report ; /* when we did that (in ticks) */
if (ticks < last_report || (ticks - last_report) >= hz) {
last_report = ticks;
printf( < error message > );
}
}
