Unknown job stuck in activity monitor

https://www-secure.symantec.com/connect/forums/how-remove-unknown-error#comment-6505811

To clear jobs as you've described from the activity monitor you will need to do the following from the master server:
Record all of the job IDs that won't cancel
Stop NetBackup
/usr/openv/netbackup/bin/bpjobd -r <jobid>

...

All depends on what version of NetBackup you are running - you signature says 7.1 and earlier so assuming that is the case this is what to do:

First off these are usually caused by a process crash some where - always worth investigating what errors on your system you had at around that time - it may also have been a server reboot just as a job was kicking in - plenty of possible reasons...

To get rid of it make a note of the job id (227858)

Make sure nothing is running, incomplete or suspended - so this rogue job is the onlything active.

On the Master Server shutdown NetBackup and make sure all processes have ended (not while any jobs are running or you may get more of these errors!)

Next, on the Master go to <install path>\netbackup\db\jobs\ and delete the bpjobd.act.db (do not delete the bpjobd.db!!!)

Then look under the ffilelogs folder for the file with that job id and delete it

Then look under the trylogs folder and do the same

Then start up NetBackup again

That should have got rid of your orphaned job

Now do some digging to see if you can identify what you had a crash / reboot/ restart at that time ( as no time is shown use the jobs either side to get an estimate)

Hope this helps

Just in case you on 7.5 there was an issue and an eeb created :
