Random crashes/failures on Linux Aarch64

[David Holmes]

Just a heads up that in recent times (still collating data) we have 
noticed quite a few seemingly random crashes, and failures, on Linux 
Aarch64.

Still collecting data and trying to see the pattern(s) here, but was 
wondering if other CI's have also been seeing any issues?
