Hangfire has taken more time to process a Job

Hi There,

Sending emails from our App was taking more time. So we decided to make use of Hangfire to take responsibility of sending emails. After the hangfire configuration we moved the same to production, and it worked well for couple of years. But now all of a sudden Hangfire has taken more time (almost 10 hrs) to process a job. I didn’t see any clues in our application/sql server logs.
Can anyone help me out with Why Hangfire took so much time to process the jobs.
