This problem is new and 100% reproducable. I've tried rebooting,
which should fix any intermittent problem. Also the RAM is from
Crucial, and I'm not doing any overclocking of any kind. Everything
else is 100% stable, except for samba, which crashes.
Turns out that it doesn't crash until a client tries to connect.

That's the first thing I fixed. Didn't help. Any other ideas?
Apparently, the crash is here:
>> #6 dns_register_smbd_reply (dns_state=0x0, lfds=0x7ffff4963ed0,
>> timeout=0x7ffff4964060) at smbd/dnsregister.c:171
I'm going to pull the source and see what's there.
