DefaultJobExecutor job status update problem case



recently I came across such a scenario.

A job finished successfully but the db status couldn't update from Done = 16 status to Scheduled = 4 because of a temporary db problem.

So this job's status stuck to Done and never schedules again.

What can be done about this?

There is no built in capability to handle this type of case I'm afraid. Best solution would be to implement a retry policy in the Linq2SqlJobStore (or your own), but there are no plans to handle this edge case atm.
