UPDATE: DDOS Taking router offline

Update: A DDOS was knocking the router offline. See second post for info and more questions!

Running v1.8.5beta2 (Tried 1.8.5 also)

I'm havingsporadic connectivity issues. So far I don't see any errors in the logs when I lose connectivy

I almost thing the interfaces are locking up because when I get back on the box all the BGP sessions timers are about the same.

Box is passing about 150M of traffic on average.

Anyone else having simillar issues?
