[exim] Exim restart all 12 MINUTES in outgoing queue.

Hi!

I have very strange problem with Exim. If someone have a idea where to look
or can help.

I use Exim and Mailscanner with ingoing and outgoing seperate queue.

Exim restart all 12 MINUTES in outgoing queue log.

/var/log/exim4_outgoing/mainlog
17:36:11 exim 4.72 daemon started: pid=7531, -q30m, not listening for SMTP
17:36:11 exim 4.72 daemon started: pid=7534, -q30m, not listening for SMTP
17:48:12 exim 4.72 daemon started: pid=9292, -q30m, not listening for SMTP
17:48:12 exim 4.72 daemon started: pid=9295, -q30m, not listening for SMTP
18:01:12 exim 4.72 daemon started: pid=11436, -q30m, not listening for SMTP
18:01:12 exim 4.72 daemon started: pid=11440, -q30m, not listening for SMTP
18:12:11 exim 4.72 daemon started: pid=13231, -q30m, not listening for SMTP
18:12:11 exim 4.72 daemon started: pid=13234, -q30m, not listening for SMTP
18:24:12 exim 4.72 daemon started: pid=14746, -q30m, not listening for SMTP
18:24:12 exim 4.72 daemon started: pid=14749, -q30m, not listening for SMTP
18:36:12 exim 4.72 daemon started: pid=16591, -q30m, not listening for SMTP
18:36:12 exim 4.72 daemon started: pid=16594, -q30m, not listening for SMTP

As well, I have this
QUEUEINTERVAL='30m'
QUEUERUNNEROPTIONS='-DOUTGOING'

I discovered the problem when I saw many "/usr/sbin/exim4 -oP
/var/run/exim4/eximqr.pid -q30m -DOUTGOING" process running. Number of
process grow by the time and finish to heat all the ram. Apart from this
problem all the remainder goes well.

I use exim 4.72-1 and mailscanner 4.79.11 on a Debian Lenny box. I
discovered the problem some time after to have upgraded mailscanner.

Thanks in advance,

Stephane
