I recently saw the following in our syslog debug output..

debuglog.0:Jun 6 20:41:36 ter2.mel.sprint.com.au error: port S9 stopped too lon
g - flushing packet queue

I then hunted the portmaster-users archive and found I am not the only one
with this problem.

The general consensus was the problem occurs when flow control is not correct.

I then made a change to the client pppd setup, where I removed the "modem" option..

>From the pppd man page..
modem Use the modem control lines. On Ultrix, this
option implies hardware flow control, as for the
crtscts option. (This option is not fully imple-
mented.)

The use of the modem control lines and the effects of the
modem and local options are not well defined.

Doing so resolved the problem of flushing packet queue's, which were previously occuring about every minute.

Anyway heres the configuration for those in the same boat..
