/etc/init.d/MailScanner stop: caught SIGTERM, aborting

Hi,
For whatever reason I can not stop/start MailScanner cleanly:

# /etc/init.d/MailScanner stop
* Stopping MailScanner...
* MailScanner: caught SIGTERM, aborting

# /etc/init.d/MailScanner start
* WARNING: MailScanner has already been started

Actually, MailScanner stops, but sendmail which has been
started by MailScanner init script is still there running:

# ps -e | grep sendmail
18676 ?        00:00:00 sendmail
18679 ?        00:00:00 sendmail

Even when I killall sendmail, I still get the above mentioned
warning, and can not start MailScanner. And that is a problem,
because MailScanner is restarted (in my case, just want to be
restarted, but is not) every hour to prevent eating all resources
(which it keeps eating anyway, read next). I checked /var/run and
/var/lock, there is no trace of MailScanner or sendmail running,
yet I can not re-start Mailscanner.  How can I fix this problem?


And the 2nd problem, MailScanner is eating too much memory:

# ps aux | grep MailScanner
root  8047  0.0  0.7  93148 31084 ?  Ss   13:53   0:00 MailScanner: 
master waiting for children, sleeping
root  8048  0.0  1.5 140136 64692 ?  S    13:53   0:00 MailScanner:

root  8173  0.0  1.5 140136 64696 ?  S    13:54   0:00 MailScanner:

root  8176  0.0  1.5 140140 64696 ?  S    13:54   0:00 MailScanner: 
waiting for messages
root  8177  0.0  1.5 140140 64696 ?  S    13:54   0:00 MailScanner: 
waiting for messages

~330 MB RESS, ~1GB VIRTS, is *this* normal? Unbelievable. I see it for
the first time, that my server does not have enough physical memory
and is forced to use swap. I'm affraid, I can not spend so much memory
just for MailScanner...
