Having problems with a long-running deployment being timed-out (Wildfly 12 Final).

Here is a solution I have tried (we have domain mode): https://gist.github.com/mcupak/20de64f0b8c7f326607612837a38997d but no success. Right after the deployment is completed (takes 15 - 20 minures, loading staff from db etc.) Wildfly shuts it down treating as 'unstable'.

Thanks in advance for any suggestions!
