RB1100AH - All PPP connections stop routing traffic

RouterOS General
1

Hi guys

I have an issue on a RB1100AH running version 6.12.

The router is used to terminate a few wireless clients that all have RB750’s and they connect using l2tp.

PROBLEM: From time to time (its really quite random) all of the tunneled connections hangs on the router. It also has 3 x PPPoE ADSL connections, 2 outbound l2tp connections etc and those inbound l2tp connections from the wireless clients.
The router still works fine and routes traffic on its Ethernet ports but only the tunneled (pppoe, l2tp etc- in as well as outbound) tunnels stop routing traffic. It has been like this even in 2 versions back.

Here is a screenshot showing the ppp client list, there is almost no traffic going through them:

Can you guys please point me in the right direction?

Thank you very much.

Use RouterOS 6.13

Thank you for the reply. I did install it on Friday and will see how it goes.
From the release notes I did notice the : *) l2tp - fixed occasional server lockup; note so hopefully it was related to that.
