Hello all,
I have a problem with an incosistent mdbox:

I use:
Dovecot 2.0.19-0ubuntu1 Ubuntu 12.04, x86-64, Kernel 3.2.0-32-generic local XFS filesystem for the mdbox
The problem appeared out of nowhere. Many messages been continously delivered to this mailbox on this installation since May 2012, and the mdbox was only accessed with deliver and imap/pop3 from dovecot. About four hours after the problem initially appeared, I did a hard reset of the system because it was unresponsive. The error message is exactly the same before and after the hard reset. The problem is triggered by both IMAP access and dovecot deliver access.
The whole mdbox is 6.6 GiB large and I guess that it contains about 300k-600k messages. It's an archive of public mailing lists, so I could give access to the files.
Can anybody say something about this? May the mdbox be repaired?
