Hangfire - Schedule job fires unexpectedly

bug?
, ,
1

I have set up 5 jobs to run at 4pm/5pm/6pm/7pm/8pm daily. This jobs emails reports those times. This morning, I had 5 emails at 630am as you can see by the screen shot

  1. Does anyone know why all these jobs ran at the same time.
  2. Is there a better way to set up the CRON to run them at 4pm/5pm/6pm/7pm/8pm week days?

BTW it is showing the next execution correctly. and current time is 120pm Thanks in advance

Update: Using 1.8.0-Beta4

Update 2
I saw there was a process that hung last night. The SameDay 7pm and SameDay 8pm, didn’t get fired until 620am this morning. I am not sure if it failed and was retrying. Seems like a very long window of retrying (about 12 hours). I cant have the report being sent that late. Should I put retries to 0?

Hangfire uses a progressively longer delay between retries, so yeah, once you get toward the last few attempts, it could be quite a bit later.

So, as you suggested in your last edit, you could set retries to zero if you didn’t want automatic retries (Dealing with Exceptions — Hangfire Documentation). That might be a bit extreme - maybe just lower the max to something between 3 and 5? That way you get some automatic requeuing, but the job will hit the failed state sooner.
