From version 5.x we have problem with our core router. We have it on 3 diferent server, but same problem. With multicore enabled, server reboot on unequable time. With multicore disabled everything is ok, but cpu is than on: 100% all time.
On version 4 we have no problem with this just on version 4.13.
I send suppout file but answer is everything is ok.
Have some same experience or solution?
