The EC2 instance that I run Dovecot on (personal mail server) was forcibly "retired" yesterday, and as a result I ended up rebuilding from backups. In the process I switched from Ubuntu Precise to Ubuntu Xenial (12.04 to 16.04), and this in turn caused me to upgrade Dovecot from 2.0.19 to 2.0.22. Now, although accessing mail seems to work OK using my various clients, I am seeing these errors in my logs: Jan 3 05:56:58 -- dovecot: imap(owen): Panic: file mail-index-sync-keywords.c: line 227 (keywords_update_records): assertion failed: (data_offset >= sizeof(struct mail_index_record)) Jan 3 05:56:58 -- dovecot: imap(owen): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x7aee2) [0x7fe9c08dbee2] -> /usr/lib/dovecot/libdovecot.so.0(+0x7afcd) [0x7fe9c08dbfcd] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fe9c0880a61] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_keywords+0x828) [0x7fe9c0c1fdd8] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_record+0xef) [0x7fe9c0c2079f] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_map+0x238) [0x7fe9c0c21758] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_map+0x71) [0x7fe9c0c18de1] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xd28fd) [0x7fe9c0c2e8fd] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xd2f03) [0x7fe9c0c2ef03] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_index_open+0x78) [0x7fe9c0c2efe8] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_storage_mailbox_open+0x92) [0x7fe9c0c08042] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x5e8d2) [0x7fe9c0bba8d2] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x5e9b8) [0x7fe9c0bba9b8] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x37b86) [0x7fe9c0b93b86] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_open+0x20) [0x7fe9c0b93d00] -> /usr/lib/dovecot/libdovecot-storage.so.0(index_storage_get_status+0x20) [0x7fe9c0c073b0] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_get_status+0x37) [0x7fe9c0b940e7] -> dovecot/imap(imap_status_get+0x77) [0x55d3b4c3f977] -> dovecot/imap(cmd_status+0x1a9) [0x55d3b4c32969] -> dovecot/imap(command_exec+0x9c) [0x55d3b4c3806c] -> dovecot/imap(+0x193e2) [0x55d3b4c363e2] -> dovecot/imap(+0x1946c) [0x55d3b4c3646c] -> dovecot/imap(client_handle_input+0x165) [0x55d3b4c36825] -> dovecot/imap(client_input+0x82) [0x55d3b4c36db2] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x4c) [0x7fe9c08efc6c] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x101) [0x7fe9c08f1101] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x25) [0x7fe9c08efcf5] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7fe9c08efe98] Jan 3 05:56:59 -- dovecot: imap(owen): Fatal: master: service(imap): child 18289 killed with signal 6 (core dumped) I have deleted the dovecot.* files in the Maildir for all users (did this while Dovecot was stopped, then started it again), but the errors persist.

Hi! The problem seems to occur during mail index processing. Can you try deleting all dovecot.index* files under this user's maildir. There might be some more under various folders.

Thanks, you were right, I had forgotten that there would be indexes for each folder (of course). So I had done a 'find -maxdepth' type command to find and delete them, and only hit the ones in Maildir. Now that I have deleted all of them, there are no more errors.
