Darn. This is caused by mailbox corruption again. My script to detect

Yeah, I was going to say.
It's corrupted cache file offset pointers. Assuming you upgraded
this from an earlier version of Cyrus at some point,
I believe we started at 1.5.19 and then migrated up through the 2.0 ,
2.2 series. Our last major update was from 2.2.13 to 2.3.11. Currently
on 2.3.13
cyrus.expunge
and cyrus.index files had issues maintaining cache pointer
consistency. You pretty much have to reconstruct all your mailboxes
to guarantee consistency I think.
This latest list of corrupted mailboxes includes many that were
correupted a couple of weeks ago (including mine) so this is the second
time they have been reconstructed.
I'm tempted to protect the code from crashing though... we don't
use unexpunge at FastMail, which is probably why I haven't already
done so.
Something like the attached should do it. I'll test it more
completely and commit it to CVS for 2.3.14 (since Ken hasn't
cut a release candidate yet!)
Thanks for the patch.
Would ipurge be causing the corruption? We currently purge e-mails older
than 31 days on a weekly basis. I will turn that off for a bit (since
disk space is not as much of an issue as it used to be) and see if the
corruption returns.
