An update to this.

I've looked at the system logs (/var/log/syslog) and monitored it as I was starting up ES.

I saw this in the logs:  
Feb 19 11:19:03 AZUREMACHINE kernel: [2075710.797219] Call Trace:  
Feb 19 11:19:03 AZUREMACHINE kernel: [2075710.797219] ? entry\_SYSCALL\_64\_fastpath+0x33/0xa3

Which lead me to this thread:

When we run Elasticsearch 5.3.3 on Ubuntu 17.10 after the most recent kernel update from 4.13.0-25-generic to 4.13.0-31-generic we see kernel oopses, any remedy except downgrading the kernel?

I upgraded ES from 5.5.0 to 5.6.7 and it's running now, so the immediate issue is solved. I would however like to get 5.5.0 running on this system as it's meant to be an exact copy of another system on this infrastructure.
