If the Asterisk control file (wrapper) is exiting with code 3, that means Asterisk is taking too long to start. I recommend you disable the HAAst service and manually try to start the Asterisk service directly.
I suspect you will see a long and slow (or errored) start of Asterisk. The systemd service file included with Asterisk is not ideal for cluster use and can cause slow startup. If you are using systemd please try the service file offered by Telium here:
