2422269 - BPM "Galaxy Base Service" is Failed and unable to start

BPM service Galaxy Base Service has Failed status when looking in the system (http://<host>:<port>/nwa/services):

Due to this, other BPM dependent services also cannot be started.

The failure persists even after trying to manually start the service.

As another symptom of this problem, when trying to access the Business Logs: Log Viewer screen (http://<host>:<port>/nwa/bpm-bizlog) it also fails with "Error while loading Business Logs: Log Viewer".

When checking the default trace messages (per SAP KBA 1596214), following error is found at the time when the Galaxy Base Service is getting started:

Service [tc~bpem~base~svc] failed to start; nested exception is:

java.lang.IllegalArgumentException: Given value does not match to a business log level.
