il processo BGP battr chunk fa da ago della bilancia.. come vedo cosa
ha in memoria?
perchè qualcosa che riempie i 225M contro i ~70M ce l'ha!
note:
l'uso della memoria sul R1 è aumentato da qualche giorno senza nessun
cambiamento di conf sui router.
il soft-reconfiguration è disabilitato.
ho cercato di scrivere poco e fare piu output possibili per la vostra
(mia) felicità! :)
