Hello!

We have CCR1036-8G-2S+ acting as pure router. Simple routing + OSPF + few simple queues (75 for present), firewall off. Client configured with a simple queue

52 name="175:433" target=VL1.251 parent=none packet-marks="" priority=8/8
queue=default-small/default-small limit-at=0/0 max-limit=500M/500M
burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s bucket-size=0.1/0.1

Already twice we got the same bug - when there is a big traffic load from client (about 800Mbit/s) CCR got 100% CPU usage, OSPF dropping links, snmp stops responding. This traffic continues for a short period (about 1-3 minutes) so we can't gather more info. The traffic is spontaneous, so we can't predict it. So, the question is: how to avoid this situation? Will upgrade to 6.39 help? Or may be other solution?

Regards,
Boris
