I've upgraded both my AX90X's to the beta (9.0.0.4.388_32094-ge476ac0), leaving AIProtection and IP6 off for now, but so far so good (~30 minutes without issue)oddly, after the upgrade - my logs no longer show the May 17 series of "NBUF alloc failed"...

I'm also struggling - abundance of caution I disabled IP6 and AIProtection to be safe, trying to decide now between the beta and downgrading the firmware?(I have two AX89X's connected with ethernet backhaul)
