Error with dovecot 2.2.14rc1

[Mark Sapiro]

I don't know if this is significant or not, but it is at least unusual here.

Oct 9 10:10:03 sbh16 dovecot: imap(mark): Error: Sync failed for mbox file /var/spool/mail/mark: seq=393 uid=201517 uid_broken=0 originally needed 0 bytes, now needs 66 bytes

which has apparently added 66 bytes to UID 201517

Oct 9 11:26:19 sbh16 dovecot: imap(mark): Error: Cached message size larger than expected (32353 > 32287)
Oct 9 11:26:19 sbh16 dovecot: imap(mark): Error: Corrupted index cache file /home/mark/Mail/.imap/INBOX/dovecot.index.cache: Broken physical size for mail UID 201517
Oct 9 11:26:19 sbh16 dovecot: imap(mark): Error: read(/var/spool/mail/mark) failed: Cached message size larger than expected (32353 > 32287) (FETCH BODY[] for mailbox INBOX UID 201517)
Oct 9 11:26:19 sbh16 dovecot: imap(mark): Disconnected: FETCH read() failed in=10948 out=1206206

As of now (almost 22 hours later) these are the only dovecot Error
messages in the log.

Going back a full month, we see this under dovecot 2.2.13

Sep 9 10:18:01 sbh16 dovecot: imap(mark): Error: Sync failed for mbox file /var/spool/mail/mark: seq=198 uid=198968 uid_broken=0 originally needed 0 bytes, now needs 66 bytes

but no subsequent errors like yesterday.
