In addition to Talend native logs for handling base logs, we use a Joblet that purges logs and adds an additional log table. This joblet is to be integrated in each job launcher. My problem is this: if the log base is not available, the full processing fails, although the "Stop on error" option is not checked in the joblet. Do you have a track for a job to run if the log base is unavailable?
Check for its presence first and use RunIf connectors to the component that starts the processing if the logs are there. You can use the RunIf links to create conditional logic to avoid certain paths in your jobs
