I went through and re-init both of the databases on the problem
machine, but still get the same errors.  Also, if I restart FDS on the
box, it claims to have been shutdown in a disorderly manner, even when
I use stop-slapd.  There are no errors related to the shutdown.

It sounds like the BDB backend is pretty hosed, and even the auto
recovery isn't completely handling it.  Ideas?
Does this happen every time with restarting the server, the disorderly shutdown in the errors log? If so, does it recover the main database? If so, I think perhaps the changelog db is corrupted. Try shutting down the server and removing the changelog db.

Do you have another master?  If so, just perform a replica initialization

We've got three other masters, but we don't use the console -- or have
X installed or heads on the machines.  Can this be done from the CLI,
maybe with mmr.pl?
Not sure about mmr.pl, but yes, this can be done via ldapmodify.
First, you have to find the DN of the replication agreement from another master
to the one you want to initialize.
ldapsearch -x -h othermaster -D "cn=directory manager" -w password -s sub -b
cn=config "objectclass=nsDS5ReplicationAgreement" cn nsDS5ReplicaHost
nsDS5ReplicaPort
There may be several, you'll have to figure out which one goes to the master
you want to initialize

Next, use ldapmodify to start the repl init:
ldapmodify -x -h othermaster -D "cn=directory manager" -w password
dn: dn of the repl agreement
changetype: modify
replace: nsds5BeginReplicaRefresh
nsds5BeginReplicaRefresh: start

Then check the error logs for both masters to see when repl init is completed.
