Unfortunately we can also not see what has been changed in the patched
RPMs you got from RH.

NetApp often sounds like NFS but you told us you are not using NFS but FC
attached disks? If so I don't know why it shouldn't work exactly as local
disks would.

But when I hear Horde/IMP I remember a problem that some people hit after
upgrading Horde/IMP. I don't remember what it was but you should find it
in the archives. IIRC it has been fixed in the latest version of
cyrus-imapd.
