Subject: user ppp does not hangup after timeout - why?

I've configure user ppp, and using it to dial out to my ISP. However, for some
reason, ppp does not hangup after the idle timeout. How do I find out what
process is holding the line, or what I've done wrong?
I start user ppp with "ppp -auto ndc".
I have not sendmail daemon running. There is a process that says sendmail is
accepting connections. Is this the cause?
I did start up the web server httpd, but there should be no incoming
connections for it. I just don't see anything else.
