Canceling job if error

[AlexeyMRX]

Can you advise on what to do if a critical error occurs during job execution?

For example, let's say the job sends data to the database every 5 minutes and then sends an email with information about the transferred data. At some point, the database becomes unavailable, triggering an exception that should result in an email notification.

However, sending the email fails because the mail server is also unresponsive.

Ideally, I would like the program to stop executing altogether. How can this be achieved?

Currently, my program continues to run as if nothing happened in the next 5 minutes, and this cycle repeats indefinitely. I'm struggling to figure out what intervention is needed.
