Hi,

The interesting point is why do you see those problems and others do not.
Since you are running a rebuild of stock RHEL6 cyrus-imapd package it
seems like others should have the same problem since it's out for quite
some time.

You can not directly go back because of the "upgrade some of the
datastructures". While I can suggest running 2.4.10 I'm quite sure it
should also work fine with 2.3.16. So there may really be something wrong
with your system. I'd try to find out first what's going on.

I could send you my 2.4.10 rpms for EL6 (i686 or x86_64) for testing, but
I don't think it's a good idea to upgrade your production box if you may
want to go back to 2.3.16 later.
