RB941-2nD periodicaly rebooted after upgrade to ros 7.5

HI, i have trouble with my router, RB941-2nD periodically rebooted after upgrade to ros 7.5
in log see this:
router was rebooted without proper shutdown
kernel failure in previous boot
out of memory condition was detected.

have anyone ideas what that and how to solve?

The only solution is downgrade to ROS v6. hAP lite has insufficient resources to run (current incarnations of) ROS v7.
