Recurring job stuck in processing after Azure DB transaction exception, blocking other jobs in the queue

Hello, we are using Hangfire 1.7.32 and are having an issue with a recurring job running on an Azure instance, it sometimes to intermittently get stuck in ‘processing’ despite the function no longer running. Since we’re set up to run one job at a time, this prevents other enqueued jobs from running until we delete the stuck job and restart the server.

Samples of our code is as follows:

To schedule the job, we call:

RecurringJob.AddOrUpdate(() =Start(), cron, Shared.GeneralUtil.GetLocalTimeZone());

The contents of Start() include:

public static void Start()
{
    int logId = default(int);
    try
    {
        (db intensive work here)
        (EXCEPTION THROWN HERE)
    }
    catch (Exception ex)
    {
        (try and clean up after exception)
    }
}

The exception details are as follows, and notably the Start() function ends immediately upon hitting this exception, so despite being occurring in the try/catch, the catch block doesn’t run:

Inner Exception 1:
SqlException: The transaction log for database 'test10' is full due to 'ACTIVE_TRANSACTION'.

If we cannot always prevent these transaction exceptions from occurring, is there a way we can at least automatically clean up the currently processing job after them so we can move on to the next enqueued job?
