I'm running NetBSD 1.5.1, and nothing complex. ntpd core dumped after running for about 2-3 minutes, soon after it came into sync with the server. A gdb on the core dump hit the heuristic fence post and I haven't had time to look further. Is anybody _successfully_ running ntpd on 1.5.1 so I can at least conclude it's site or host specific? Maybe someone knows what's going on? There's nothing spectacular in the logs. Thanks, - Joel
