Hi,

we are runnning 4 ccr1036 in a line connected on both ends to our ospf area0. sometimes one of these ccr's drops all ethernet ports and is not reachable anymore. we receive some logs like

ether5 link down
ether6 link down
ether7 link down

the connected dedices on these port's do not loose their ethernet link. ccr does not respond to ospf and arp anymore.

we experienced this on all 4 of them at different time.
we did not have a chance to access them via serial console on case of failure.

we did see one magic healing of one device after 18h of beeing down. nothing in the log except ethernet down, ethernet up.

we run ospf, little bit of bridging vlan's und one vpls between two of them which are directly connected.

did anyone see something like this? we saw this in 6.12 and 6.15.

Mikrotik supposed to go for 6.19rc with netinstall to get a clean base.

Nils
