I'll look at reproducing it again.
In this particular case, the master had a database rooted at "", with some
data around "cn=zimbra" contained in it. A replica was configured as a
syncrepl client, but with "dc=example,dc=com" as its base, by mistake.
This resulted in the CPU usage shooting to 100% on the replica, and the
logs showing it trying to add without success.
