slapd randomly dieing with "bus error"

which usually means some array is out of bounds, but I have 0 idea how to fix it(and our high paid Apple support contact has been, in a word, useless)

It all started with passwordservice crashing after using the GUI to add a user. Now every couple of hours I get a message in the console that slapd has died. It relaunches right away, and the users don't seem to notice, but it isn't anything I feel very comfortable with. Anyone ever seen this before? To top it off, after the latest crash I'm getting tons of "Server not found in Kerberos database" errors on the console too....

I feel like I am beta-testing their products
