Has anyone else experience the CCR1072 running 6.43.8 and the previous couple releases, becoming unstable and crashing (total hang up requiring a power cycle to recover) when running packetsniff?
A big clue is the CPU goes to 100% when running packet sniff. Even a sniff that results in a rather small capture.
After the sniff stops, the CPU value does not return to where it was before the sniff. And each additional sniff causes the CPU to get worse and worse then finally the router just locks up with no response.
No console messages either. Have to power cycle the unit to recover it.
Its running with 3-5GBps customer traffic.
About 60 Firewall rules.
Some NATs for customers on private IPs.
BGP peering to upstream.
FastPath and FastTrack turned off.
I’m not sure where to go and MT support does not have any answers other than to lighten the load by reducing connection tracking using RAW rules.
Cannot really do that.
Has anyone else see this?
