Failed job is not triggering

We have multiple jobs running and few jobs throw exceptions sometimes.
But those jobs gets re-triggered as per cron expression. But recently we faced an issue where one of the job throw an exception and its been 3 days the schedular is not running.
The exception was : could not commit jpa transaction

Also, this schedular has delegateExpression whereas other schedular have implemented java class.

Is there a way we can re-run the schedular again as deployment/restart is not we want to do.
