Hello everyone,
I remember that Timo wrote in this maillist that if index files are corrupted, dovecot should be OK and just recreate it. So I report here a bug: I have corrupted indexes which make pop3 and imap processes to hangup right after the first list command. The process does not respond and eats 90% of CPU. Just unpack http://redin.info/dovecot-corrupted-index.tgz (10 Kb) into a user's IMAP root (I have mbox storage, but the same thing for maildir with this indexes), do the chown, and try to check the email.
I know that the problem can be fixed by removing the index files or using INDEX=MEMORY, but it is claimed that dovecot is failsafe and can deal with any kind of corrupted index files. This is the only reason why I report it here.
I have 1.0.alpha4 on FreeBSD 4.11 (installed from ports).
Best regards, Sergey Redin.
