I'm running Dovecot on a Debian system which recently has been
failing on an assert(). I have a spam mailbox that if I try and open
(from any client), the imap process dies and this is written to the
error logs:
Dec 21 18:57:11 theronge imap(mronge): file imap-bodystructure.c:
line 278 (part_parse_headers): assertion failed: (part->physical_pos
>= input->v_offset - start_offset)
Dec 21 18:57:11 theronge dovecot: child 28911 (imap) killed with
signal 6
I had this same issue with my Inbox a few weeks ago, so I moved all
the e-mail out and moved each piece back in one by one, in order to
determine if a piece of mail was causing the issue. As soon as all my
mail was moved back in, the issue went away and I was able to load my
Inbox as usual. I still have the same issue with my spam mailbox, is
there anything particular I can do to help debug this issue? In the
past I've rm'ed all the mail in my spam mailbox and that fixes it.
One thing that may be related is that I only noticed this issue after
I had setup Spambayes, which does it's work via procmail. The
mailboxes that I've had the issue with, all had headers that contain
a Spambayes header, usually like so:
X-Spam-Score: 26
X-Spam-Score: 0.6 (/)
Sender: mailman-bounces at acm.uiuc.edu
Errors-To: mailman-bounces at acm.uiuc.edu
X-Spam-Score: 0.1 (/)
X-Authenticated-Sender:
X-Spam-Details: rule=cautious-plus_notspam policy=cautious-plus score=26
mlx=26 adultscore=0 adjust=0 reason=mlx engine=3.1.0-0611300000
definitions=main-0612060023
X-Spam-OrigSender: mailman-bounces at acm.uiuc.edu
X-Spam-Bar: ***
X-Spambayes-Classification: spam; 1.00
X-Spambayes-Trained: spam
I'm not sure if it's related, but it's a shock in the dark on my
part. Any suggested steps that might help isolate this bug?

The problem is that Dovecot has stored a cached MIME structure into dovecot.index.cache file, but now when it's trying to use it again, mail's contents have either changed or something else weird has happened. I think I had added several sanity checks to this already, so this assert shouldn't really have happened. But the same problem has existed for years, so this is getting a bit annoying problem. Could it be possible that the mail's body had changed? Anyway if you delete dovecot.index.cache file it should work again. -------------- next part -------------- A non-text attachment was scrubbed...
