Resolution

Check the permissions on the /opt/IMDataAggregator/apache-karaf-<version>/deploy/ directory.

It should be owned by the non-root service account that runs the DA processes. If it is not take these steps.

1. Stop the dadaemon and activemq services.
2. Change ownership to ensure the deploy directory is owned by the proper user.
3. Start the dadaemon and activemq services.
