atd stuck jobs in queue

  • 772

I am on Bionic (18.04.4) and I see that my jobs are stuck in the queue and never run!

[root@myhost2: log]# atq
3267   Tue Jun 16 03:34:00 2020 = root
697    Mon Jun 15 19:36:00 2020 = root
3268   Tue Jun 16 03:34:00 2020 = root
3265   Tue Jun 16 03:31:00 2020 = root
7566   Tue Jun 16 22:17:00 2020 a root
7563   Tue Jun 16 22:16:00 2020 a root
697    Mon Jun 15 19:36:00 2020 a root

The file being pointed to (a002b90194efbc) is empty!

If I delete the files in spool and reboot it becomes ok, but not sure when it might go back to the same bad state!

How do I make sure to never get into this stuck state!? Or, if stuck, any way to auto recover?

-- Thanks
