RB2011 unaccessible - possibly related to ipsec/l2tp/ospf

I’m experiencing issues similar to what is described in the following topic: http://forum.mikrotik.com/t/rb2011-freezing/75538/1

system: rb2011uas-2hnd
ros: 6.12, 6.10

The router simply isn’t accessible over ethernet/wifi after a while.
I still didn’t have the time to connect over the console once this happens.

Symptoms: losing l2tp connectivity due to ipsec failing (SA getting lost after a while), on one occasion i noticed the switch got into a hub behavior (packets from other ports visible).

I’m suspecting this might be related to either ipsec/l2tp or even ospf i’m running between those routers.

Anyone experiencing this as well?

Install 6.12, after the problem send supout.rif to support@mikrotik.com with problem description.
