Problems with Cyrus IMAP 2.2.5 on Solaris 9 on production server

[Shawn Sivy]

Against my better judgement, I upgrade the hardware Sun 280R to Sun 440,

the OS from Solaris 8 to 9 and Cyrus IMAP 2.0.16, SASL 1.5.24 & Postfix 
1.1.13 to IMAP 2.2.5, SASL 2.1.18 & Postfix 2.1.1.

I haven't created any new users on the new version yet.  I did try going 
from quotalegacy to skiplist for quota_db, but I couldn't add create any 
quota for users.  In cyradm the "lq" command would work until I set the 
quota on the first user, then both lq and sq would hang.  The initial sq 
was reaaal slooow too (compares to create a quota with quotalegacy).

I can try "downgrading" to Imap 2.2.3.  Nothing has changed as far as 
the structures (cyrus.* files, etc.), so I should just be able to 
compile and install that version right?
