It might not be a fault in dovecot, as the user is accessing the folder locally
with alpine while also running imap-sessions. However it would have been nice
with a more graceful action than panic?
The panic is preceeded by
Error: Next message unexpectedly corrupted in mbox file PATH
Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed:
(sync_ctx->input->v_offset != mail_ctx->mail.from_offset ||
sync_ctx->input->eof)
At #7 in the enclosed backtrace the actual values are
sync_ctx->input->v_offset = 564
mail_ctx->mail.from_offset = 564
sync_ctx->input->eof = 0
Some will recommend convertion to maildir, but with 25 years history, thousands
of
active users and dozens terrabytes of mboxes, we are not even considering it.
