DBERROR: skiplist recovery errors

[John A. Tamplin]

I have a user mailbox that is genering thousands of these same "DBERROR: 
skiplist recovery: xxxx should be ADD or DELETE" messages.  This machine 
hasn't been rebooted, and Cyrus hasn't even been restarted since this 
particular user was converted (on the Cyrus side, conversion entails 
simply doing multi-appends via IMAP).  This is 2.1.11 on Solaris 9.

It seems like this has to be some bug in the skiplist code.  This user 
does have one of the larger mailboxes (1121 folders with 534M of total 
mail), but there are some with larger.  What information would be 
helpful to track down the problem?

Is there any way to recover the seen state of this user?  I know I can 
delete the .seen file and it will recreate it, but I am sure this will 
be an inconvenience to this user and why would I expect it to not happen 
again?
