Hi, just found my router being unable to reestablish the PPPoE connection this morning. This had been going on for about four hours before I restarted ppp. Any ideas what would cause the output queue to choke, why it would report Already in NETWORK phase, why the output queue is choking, and why ppp can't successfully clear it?
