we have narrowed the problem to this: every time we add a value to a
multivalued attribute for a particular dn, slapd dies. And the attribute
value does not get added.
Below is the output from a wrapper we use for ldapmodify.
Could this be db corruption? The particular attribute is not indexed.
If you suspect a libdb issue, you could run db_recover within your
db directory; remove and re-add that particular dn; or slapcat/slapadd
To be safe, you should backup the contents of your db directory and/or
slapcat your db before attempting recovery.

Will setting the logging to DEBUG provide anything?
I think that would depend on how the section of code which generates the
abort is coded. If it produces debug output just prior to calling abort,
then you should see that.
Also, I have a question about debugging a corefile. Our production
fo slapd does not have debug symbols compiled in. If, on a non-production
machine, we were to compile another instance, when the same libraries,
etc., but, with debugging turned on could we run gdb against the corefile
we dropped in production against this executable?
I don't know the answer to that.

Which versions of slapd, libssl, berkeleydb, and libsasl are you running?
SIGABRT implies that the process ended due to an unexpected condition
occurring within either a library or slapd itself. Were any core dumps
generated? If not, enable core dumps and get a backtrace from within gdb.
It should point you to the section of code which is triggering the abort.
