I've had a few cases on extremely busy systems with multiple
replicas/mmr nodes where they literally never catch up. Only way I've
been able to resolve those cases is to stop them, slapcat the master,
slapadd, and restart. Hopefully this change would alleviate that scenario.
Yes, I'm seeing the same thing. And yes, that's my hope as well. Not
sure if it's enough; like I said there are other performance issues in
the consumer code.
