I upgraded 2 of my boxes yesterday to Router OS 3.4 and seem to be having a problem with the PPPoE Server. After the upgrade everything worked fine, but I notice that after sometime, it kills the PPPoE connections and doesnt allow any new connection on. When I watch the logs to see if any client is trying to connect via PPPoE, all I see it the attempt to connect and it immediately disconnects without trying to authenticate. The only remedy I have found so far, is when it does this, I reboot the unit and all comes back ok for another 2 or 3 hours after which the problem starts again.
Has anyone seen this and have a solution?
