--------------------

Environment

Release : 10.7.0

Component : APM Agents

Resolution

Server was hardened so port 8443 could not come up. Issue  netstat could not run without root. Script would try 10 times to bind to port 8443 and failed. Enable set -x in start of script to see what was happening.
