Environment

Release : 21.0.5

Resolution

Troubleshooting:
Look at the service manager logs for the lines that show the process starting.  Copy the start command and the start directory.  Based on this:

cd [start directory from step above]
nohup [start command from step above] &

This threw the error:
nohup: failed to run command '[path to java]/java' [automic@server bin] $ : Permission denied

we looked at java's /bin directory and everything was rw-r---r-  there was no execute privileges, so we updated java to allow execute and the J*Ps could start
