The cuprit is probably sendmail. I had the same problem. When sendmail
started, PPP started. A quick test is to configure your system to
not run sendmail. I solved the problem by adding filters to not startup
PPP on whatever was being sent by sendmail.
See the ppp man page in the section "PACKET FILTERING". You want the
"dfilter".
