Mine is using around 80MB after a reboot. Are you running Entware or any custom options on it?
I am seeing the same issue with my 87U with the memory at 50% after upgrading from 380.69_2. Not running Entware or anything special (yet... although I am looking at the amtm script for DNSCrypt and AB Solutions). Did your find the cause/solution to the memory bloat?
