we're running a c7204 as lns to terminate PPPoE users comming in via
l2tp. Authentication and accounting is handeled by radius. Sometimes
after 1 day, sometimes after 3 days all ppp sessions gets down, no
re-login is possible.
At this time i see many errors in radius.log like "Error: rlm_radutmp:
Logout for NAS lns1 port 233, but no Login record"
After reloading the cisco all works fine for 1-4 days.
Any hints ?
