Environment

Release : 21.0.4

Cause

Two possible causes:

• This can be caused by either being out of space

•  

  This error can be caused by multiple users (i.e. root) starting the Java proecesses (JWP, JCP, REST) and files in the AutomationEngine/bin/configuration folder being owned by those users and not being able to be re-written or accessible by the user attempting to start the java processes (ie. user automic).  

Resolution

Check to be sure there is enough space on the drive and for the user starting the service manager or J*P process

Change ownership using the command: 
chown automic:automic -R ./configuration/ 
from the AutomationEngine/bin folder
Then the java processes were able to start
