Got one! (This is after switching back to a 2.4 kernel -- I was on 2.6.1 for
the last week or so, and that was the entire time I had the debugging
version of samba runing too, so there's some kind of "child exiting before
parent notification" that is happening in 2.6)

Hmm, do I need to compile my libc non-stripped, or is the problem in
tdb/tdb.c:1498?

The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for pid 2214 (/usr/sbin/smbd).

Below is a backtrace for this process generated with gdb, which shows
the state of the program at the time the error occured.  You are
