Cyrus 2.2.8: imapd dies + corrupt inbox

Dear Cyrus community,

Cyrus IMAP 2.2.10 did not fix the problem with crashing imapd processes.
I have opened a bugzilla for this

   https://bugzilla.andrew.cmu.edu/show_bug.cgi?id=2617

and hope somone might have a look at this. I can provide core files but
I don't want to post them as bugzilla attachment since they may contain
sensitive information.

Thanks in advance for help.

Regards,
Bernd
