known issue on MK762x devices in 19.07.4

fixed in next release, 19.07.3 is OK for this bug if you must downgrade
https://bugs.openwrt.org/index.php?do=details&task_id=3332 refers

I avoid it by limiting torrent clients and speed (Warthunder game update caused havok - click on spanner/wrench icon in game client to limit speed and it didn;t happen any more)
