It maybe also worth stress testing your hardware with tools such as stress-ng
to try and coerce issues like this out. See:

Title:
CPU Cores Stalls/Lock
Status in linux package in Ubuntu:
Confirmed
Status in zfs-linux package in Ubuntu:
Triaged
Bug description:
CPU Stalls or Locks up after a random period of time. Can not trace
issue to high resources or heat. System will crash while sitting
essentially idle. Sometimes system will crash after a few minutes some
times it will take days. A large file transfer will usually force the
crash though.
I have been having similar issue since Ubuntu 14.04. I have upgrade to
every version along the way to 17.04 with the same issue. I have
replaced every piece of hardware except HDD. MB, Proc, power supply,
memory, video card. With and without AMD micro code. This is a server
so no GUI.
I've tried upstream kernels but they don't support ZFS and I haven't
had any luck shimming it in. Happy to try newer kernels if someone can
provide one with ZFS support.
