1) it doesn't happen to all t3 instances I have, but it happens quite regularly
on a small subset that have similar workloads. This specific machine is running
a few testnet blockchain nodes (bitcoin, ethereum, etc.), and it just freezed
2) I think it's happening, less frequently, also on a c5 instance, but I have
aws automatic recover on that one.
3) All these machines have multiple gp2 disks only.
