If there are any jobs that appear to be hung or stuck in a PEND (Pending) status, and need to be cleared or aborted, you can use the following CLI command to find the Job ID of the stuck job:
> show jobs all
In the example above, Job ID 4 is a stuck software download.
To clear the hung job, use the following command:
> clear job id <job_id>
In the event that any of the jobs do not "clear up" after clearing the job, you may want to restart the management server process with the following command:
PAN-OS 5.0, 6.0, 6.1
> debug software restart management-server
PAN-OS 7.0, 7.1
> debug software restart process management-server
Note: Since this command restarts that management server process, it will kick WebGUI and CLI users.
