dovecot - Oct 2005 - hangup with corrupted indexes

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.

Thanks, fixed. There already was code for checking loops inside cache
file, but it was missing from one place.

Of course, this condition should have never happened anyway..
