We have about 150 RUT240's deployed using mobile data. They all connect to our L2TP management VPN.
When there are network issues in the area, the L2TP session drops and then respawns, but the router doesn't kill the old session.
We are getting to the point where there are so many L2TP interfaces spawned that the router memory is filling up and crashing (e.g. 20-30 instances).
Is it possible this is a configuration issue? Or a firmware issue?
Most of our routers are on 7.02.04, and a few are now on 7.02.07.
