core dump! help!

We've installed OpenLDAP on our new production machines, and one just core
dumped. I wasn't doing much at all to the server -- a small sample data set
(fewer than 30 records), infrequent lookups, & even less frequent writes.
Hopefully somebody can shed some light on why this happened & how to prevent
it in the future.

We're running the following:
Solaris 7
OpenLDAP 2.0.15
BerkeleyDB 3.2 (Sleepy Cat)
OpenSSL 0.9.6b
We haven't done much configuration such as tuning memory management yet.

Unfortunately I had logging turned off (darn), and now I'm unable to
reproduce the problem (the data files don't seem to be corrupted), so I
can't say exactly what went wrong. I've turned logging on again, and we're
doing stress testing over the next few days, so I might have more info
later. All I can offer is the beginning of the core file obtained via 
strings core | more
If anybody can read this & finds something telling, would you let me & the
rest of the group know?
