Need a help on PPP service...

Hello..
i have a 300 pptp clients on my ccr1036. But after upgraded my OS to 6.39.1 version, i can’t enter my all clients. Actually all my clients in active connections and when trying to enter, clients connection will be closed. And i’ll stop, client connected again… i have no idea for this error, i checked all settings and queues. But still being in problem.. please help ASAP…

This was a OS 6.39.1 bug.

Had the same issue with l2tp tunnels.

So i disabled encryption and all of then reconnected fine
