[Dovecot] Problem with dict-quota, deliver killed by delivery attempt

Hi,

I can't get quota lda plugin working...
When I enable quota plugin, the emails (delivered by exim + dovecot-lda) are
instantly rejected:

2009-09-29 16:36:12 1MsdoI-0000aJ-2L ** jacek at my-domain.pl R=mysql_localuser
T=dovecot_delivery: Child process of dovecot_delivery transport (running
command "/usr/lib64/dovecot/deliver -d $local_part@$domain  -f
$sender_address -a $original_local_part@$original_domain") was terminated
by
signal 9 (Killed)

I have checked, that neither restart of dovecot nor delivery attempt tries
to read the quotadict file (/etc/dovecot/dovecot-dict-quota.conf) - the
atime is unchanged.

I even tried to strace deliver:

strace deliver -d jacek at my-server.pl -f joshua at another-server.pl -a jacek
at my-server.pl

[...]
and it dies like this:

I have completely no idea what is wrong - could anybody help?

Yeah, there is a bug in 1.2.5 if you're using non-Maildir++ quota. This
patch fixes it: http://hg.dovecot.org/dovecot-1.2/rev/3132464fbe9c

Although I would have expected signal 11, not 9.

My plugin settings:
  quota = maildir:User quota
  quota_rule = *:storage=2G

And in Imap:
protocol imap {
  mail_plugins = quota imap_quota  acl
}

M.A.

All right, that fixes the problem :) Thanks!
However, now I have to find out how to actually configure quota... ;)

I think grsecurity + pax kills it with "9":
