Anyone with the 89X having issues with RAM usage being really high (around 97%) followed by the router crashing on this firmware? I essentially have to reboot every two days to prevent the thing from running out of RAM.
I was able to establish a 2.5Gbe backhaul from the 89x to an 86u (which I could not do previously). I am going from 89x to 10Gbe (support 2.5 and 5Gbe as well) switch via SPF+ DAC cable, and from switch to the 86u. I image if that works then a 10Gbe backhual to another 89x will work.
