Just installed the version from CVS as of Oct. 27.
I noticed three problems quite quickly:
Still seeing "(imap) killed with signal 14"
My INBOX closed with "access error" after reading it for a bit.
There's
nothing in the logs or anything, but this hasn't happened for quite a
while now. There where quite a lot of incoming messages at the time and
I was marking messages as deleted using pine. After reverting to the
last version of dovecot that I was using and restarting pine, it opened
quickly (no reindexing) and the deleted emails where marked as deleted.
I don't know if this helps much ;-)
The rest is a backtrace, etc. of an assertion failure:

And do you mean you didn't try again with the new Dovecot, just reverted to old one?> dovecot: Oct 27 16:58:12 Error: 13481 imap(username): file > mbox-sync-rewrite.c: line 393 (mbox_sync_read_and_move): assertion failed: > (need_space == (uoff_t)-mails[idx].space)Is this from older Dovecot too?

I hoped I had fixed this yesterday.I'm now running CVS version as of Oct 28. A couple users have gotten a very similar assertion failure. Here's the log entry and backtrace: dovecot: Nov 01 05:07:18 Error: 8434 imap(username): file mbox-sync-rewrite.c: line 383 (mbox_sync_read_and_move): assertion failed: (seq == mail_ctx->seq) dovecot: Nov 01 05:07:20 Error: child 8434 (imap) killed with signal 6 (gdb) bt full #0 0xffffe410 in ??

[I am sorry about the broken threading, I do not have the original email to reply to] We are also seeing the following assertion with the current code from cvs: file mbox-sync-rewrite.c: line 106 (mbox_sync_headers_add_space): assertion failed: (start_pos < data_size) After rewriting the file by copying all email to another mbox file from an imap client the error went away. The original file contains sensitive information, but if anyone has sometihng in the file they want us to check we still have the original file. Peter
