I don't think it's hardware issue. All the hosts are VMs. By the way, using the same set of VMWare hypervisors, I switched back to Ubuntu 16.04 last night, so far so good, no freeze.

we're using debian with our own backported kernels and ceph, works rock
solid.
what you're describing sounds more like hardware issues to me. if you
don't fully "trust"/have confidence in your hardware (and your logs
don't reveal anything), I'd recommend running some burn-in tests
(memtest, cpuburn, etc.) on them for 24 hours/machine to rule out
cpu/ram/etc. issues.
