The freeze is likely a kernel panic. Try testing different versions of the kernel.

I saw random OS hang so I gave up and switched to Ubuntu 16.04. Every thing works well using Ubuntu 16.04.Yesterday I tried Ubuntu 17.10, again I saw random OS hang, no matter it's mon, mgr, osd, or rgw. When it hangs, the console won't respond to keyboard input, the host is unreachable from the network.This is the OS vs kernel version list:Ubuntu 16.04 -> kernel 4.4Debian 9.3 -> kernel 4.9Ubuntu 17.10 -> kernel 4.13Just wondering if anyone has seen the same issue, or it's just me.
