Hi all. I'm a cyrus newbie/novice. I rebooted my mailserver this morning, and 
now cyrus is dead. This is my mailserver at home so it is not critical, but 
my personal mail is kaput until I get this fixed.

After the system rebooted the disk started spinning like mad ... which turned 
out to be syslog dumping tons of log messages from cyrus. The following lines 
are repeated hundreds and hundreds of times:

Oct 17 13:28:45 o-ren master[12647]: about to exec /usr/lib/cyrus/imapd 
 Oct 17 13:28:45 o-ren imap[12647]: executed 
 Oct 17 13:28:45 o-ren imap[12647]: skiplist: invalid magic 
header: /var/imap/mailboxes.db 
 Oct 17 13:28:45 o-ren imap[12647]: DBERROR: opening /var/imap/mailboxes.db: 
cyrusdb error 
 Oct 17 13:28:45 o-ren imap[12647]: Fatal error: can't read mailboxes file 
 Oct 17 13:28:45 o-ren master[10840]: process 12647 exited, status 75 
 Oct 17 13:28:45 o-ren master[10840]: service imap pid 12647 in READY state: 
terminated abnormally

I found a note here:

http://asg.web.cmu.edu/archive/message.php?mailbox=archive.info-cyrus&msg=28119

with a fix, but that fix is not working for me. I ran conv.sh which gave me 
the following file:

I then ran ctl_mboxlist, but that seems to have given me a broken file as 
well:

o-ren root # ls -l /var/imap/

Significant size differance between the new and old files.

o-ren root # file /var/imap/mailboxes.db
/var/imap/mailboxes.db: Apple QuickTime movie file (skip)

A quicktime movie file? Something is busted ...

o-ren root # file /var/imap/mailboxes.db.bak
/var/imap/mailboxes.db.bak: Berkeley DB (Btree, version 9, native byte-order)
o-ren root #

This is the original which gives me the invalid magic header error.

I am not sure where to go from here. Any takers? Maybe my conv.sh is broken?

This is running on a Gentoo Linux PC.

Thanks,

Mark
