Every time my "updater" process writes an LDIF to LDAP, clients start seeing timeouts during authentication. Even with a small number of inserts or removals, this problem shows up.

openldap 2.4.47, MBD, 16 core Linux server, 6 nodes in a n-way multimaster replication configuration. The on disk database is 1.5gigs.

Can anyone suggest tunables for this problem? I've tried "threads 64" but that didn't improve things.
