Description

I have a simple script "manage-entity.sh process dss" that deletes, submit and schedules a Falcon process.

A couple of times per week, I get the "FalconCLIException: Bad Request;Could not commit transaction due to exception during persistence" when submitting the process.

The workaround is to restart Falcon server...

e.g.:

$ ./manage-entity.sh process dss my-process.xml

falcon/default/my-process(process) removed successfully (KILLED in ENGINE)

Stacktrace:
