It looks to me like pppd is being terminated by rp-pppoe.

For what it's worth, I don't see anything in pppd that could
reasonably be affected by whether syslogd is running or not, and
certainly nothing that would _stop_ working simply because syslogd is
there.

My guess would have to be a bug in the underlying operating system.
Whatever it is, it's obscure.

There've been many postings about this problem over the past year or
so.  I don't think anyone knows how to fix the problem.

The common components seem to be Linux and rp-pppoe.  Pppd works fine
on other platforms and when PPPoE isn't in use.

I use pppd and pppoe on my system.

... and it doesn't happen on _all_ systems, just _some_ of them.
Whatever it is, it's strange.

trace it.  Use strace and see what is going on.
