svc -t question

[Ralf Guenthner]

Hi

I installed the daemontools today, but when I tried to restart/shutdown qmail with svc 
-t /var/run/qmail the following entry turned up in the log:

May 19 17:06:19 mail-2 qmail: 927126379.724078 status: exiting
May 19 17:06:21 mail-2 smtpd: 927126380.949428 tcpserver: fatal: unable to bind: 
address already used

Why is tcpserver still running?

Thanks for any hints
Ralf
