Hello!

Here is an interesting statistics on a CCR1036 working as a BRAS (PPPoE server). See the picture:


As you see, ping RTT grows over time and resets on reboot. It may be some kind of a resource leak.

Is this the ping time between the monitoring system and the bras?

Is this the ping time between the monitoring system and the bras?

Yes, exactly.

Two other CCR1036 show similar pictures:



But two another don't:



The only difference I see now is that ccr0, ccr1 and ccr2 have a DHCP server enabled and ccr3-4 don't. So probably it is not PPPoE server that creates the RTT growth.

Here are corresponding memory usage graphs. Old routeros versions have had a memory leak, but newer ones are not so clear.
