Well, check what OE6 is talking to Dovecot. Is it fetching headers or
bodies for all messages? It should do that to only new messages.

Rawlog or some network sniffers could tell what exactly is happening.

Also is Dovecot really rebuilding the indexes all the time? How do you
know? Try the in-memory indexes, at least then it's not rebuilding any
indexes to disk.

Dovecot doesn't count them, but your OS might. I don't know really.

Hmm.. I was going to suggest trying 0.99.10-test, but I guess you're
using it now? Looks like I have similiar error messages in my log :)
Have to fix those.

You didn't say how long this load problem has been going on, was it only
recently or for longer now?
