Urgent assistance required

[Bryan Hill]

Wendell:

This error you are getting, happened to me numerous times.  It's  
Berkeley DB causing your woes.  Even the Cyrus documentation calims  
that Berkely is unstable:

"...it has proved to be somewhat unstable and prone to locking problems"
( http://acswiki.andrew.cmu.edu/twiki/bin/view/Cyrus/ 
WhatDatabaseBackend )

I'm running 10.3.9 server with cyrus.  You need to get off of the  
berekely DB format for you mailbox DB an go to skiplist.  I have a  
script that I modified that was originally part of Apples Tiger  
Server installer (found the code on Apple's CVS).  Basically in  
Tiger, they say that they are "upgrading" your cyrus databases during  
a Tiger upgrade.  In fact, they are converting the DB's from Berkeley  
to skiplist.  I took this script and took out the Tiger-specific  
parts and made it perform the conversions on the database files  
specific to Panther.

You can contact me offlist if you are interested in the script &  
procedure for the conversion.
