I have AM running on Ubuntu server 18.04. A couple days ago I reinstalled the system and since then miner freezes 1-3 minutes after it starts mining, also freezing keyboard and mouse (??). First hashrate stops showing, then temperature, if I stop it it won't start again with an error, logs show nothing useful. Reinstalling AM remote agent helps to restart the miner but then the story repeats. Have anyone else experienced this? I've remover all other software leaving raw OF and AM, increased the swap file size to 50gb, nothing helps.
