I have been getting these assertion failures every couple days, killing the IMAP process. After it happens, I can login immediately and everything is fine until it happens again. Here is the log entry:
Sep 10 10:03:41 mailbox-4 dovecot: nh: IMAP(username): file mail-index-view-sync.c: line 666 (mail_index_view_sync_end): assertion failed: (view->log_file_offset >= view->map->hdr.log_file_int_offset) Sep 10 10:03:41 mailbox-4 dovecot: child 38458 (imap) killed with signal 6
It started after I disabled indexing for deliver and IMAP:
mail_location = maildir:~/Maildir:INDEX=MEMORY
I removed the dovecot.index* files from all of the maildir directories (including the root/INBOX), but that didn't help.
I have upgraded to 1.0.5, but that didn't help either.
Any ideas as to what might be causing this?
Thanks, -Doug
