Hi!
I'm here again with a problem. I'm using dovecot as an IMAP server and LDA, filtering mail via sieve. However, few times a day I get the following error on server and my client (mutt) gets disconnected.
Oct 15 20:20:29 ibex dovecot: imap(krakonos): Error: Corrupted index cache file /home/krakonos/.mbox/.imap/INBOX/dovecot.index.cache: Broken physical s ize for mail UID 149418 in mailbox INBOX: read(/home/krakonos/.mbox/inbox) failed: Cached message size smaller than expected (3793 < 8065, box=INBOX, UID=149418, cached Message-Id=<88deda0d-86f6-6115-af10-60ac06bb2d22@rename-it.nl>) Oct 15 20:20:29 ibex dovecot: imap(krakonos): Error: read(/home/krakonos/.mbox/inbox) failed: Cached message size smaller than expected (3793 < 8065, box=INBOX, UID=149418, cached Message-Id=<88deda0d-86f6-6115-af10-60ac06bb2d22@rename-it.nl>) (FETCH BODY[] for mailbox INBOX UID 149418) Oct 15 20:20:29 ibex dovecot: imap(krakonos): FETCH read() failed in=110326 out=5115197
This is on a new message (attached), and this error happens on some messages when first opened. Once I reconnect, the message always opens fine, and no old message ever causes problem.
I also noticed this error, which is possibly connected:
Oct 15 20:15:12 ibex dovecot: lda(krakonos): Error: Next message unexpectedly corrupted in mbox file /home/krakonos/.mbox/inbox at 546862809
The filesystem is ext4, and there are no errors in syslog or problems with any other services.
I also don't access the mbox locally, and only dovecot manipulates the mbox (via imap and mailbox_command = /usr/libexec/dovecot/deliver)
The postfix version is 2.2.25. I'm attaching dovecot -n and the offending message (after it's been corrected). I'd rather not publish my sieve file, but will send it privately.
The offending message also contains other message I received at approximately the same time.
Any hint's on what could be wrong?
