The issue is caused by Azul causing ENOMEM on mlock and mlock2 calls, even though the parameters passed appear valid.
As this works in newer versions of Azul it seems to be an issue within Azul itself. There are some google hits on Azul/mlock but I didn't find anything definite on a quick scan. mlock/2 are very rarely used/needed so for now these have been changed to no-ops if running under Azul.
