Cześć,
jest tu może jakiś developer, który zrozumie ten zrzut pamięci? Mam duży 
problem ze stabilnością routera, działa 5 dni bez problemu po czym przez 
godzinę potrafi się trzy razy zrebootować. Poniżej przesyłam zrzut 
pamięci. Router jest średnio obciążony, ok 50Mbit ruchu, 3 sesje BGP z 
pełnymi tablicami, Nat (ipnat), shaping (dummynet). Może problem tkwi w 
połączeniu BGP z NATem? Ma ktoś odpalonego NATa na routerze BGP?

z góry dziękuje za wszelkie sugestie, pozdrawiam
Mikołaj
