I think that might be down to zmmtaconfig. I turned that off using zmmtaconfigctl and the peaks went away. zmmtaconfig is a perl script that seems to check processes, copy settings from the LDAP config into the variety of of config files that make up Zimbra*.
*expert advice appreciated!! It would be nice to have a detailed description of the process architecture.
Having said that, I don't think you can leave zmmtaconfig turned off without understanding the consequences - I don't, so I won't. My experiments were only to find out what was causing the spikes. I get a bit fidgety when I see a functionally idle system stabbing the CPU for some reason.
In the end, you just have to trial it and keep a close eye on it until you begin to trust it.
