lpsched problem

[Javier Ortiz Guajardo]

When i start the lpsched command i see in the top command that the lpsched goes to 98% of cpu load, after 2 minutes it begin to reduce the amount of cpu load and begin to work normal.
Also when i shutdown the lpsched with lpshut it continues active.

Is the cpu load normal?
What can i do to make lpshut work normal.

I appreciate your comments and thanks so much.

Did you patch the system properly? Check the CPU load with GlancePlus, that will give you the correct resource usages.

Remove file SCHEDLOCK from /var/spool/lp directory. If any big print jobs are waiting in the queue, then remove that first and then shutdown the lp services.

It's not normal for lpsched's load to surge like than unless you got a huge active spool file trying to reprint upon startup of the spooler or you got a corrupted print entry in your spooler. When you lpshut it and if you still see lpsched process, try to terminate it manually with the "kill" command. Wait for a while (a minute or 2) then restart lpsched. Try to lpshut it again much later and see if the problem still arises. If it does I would suggest you check each printer entry and make sure you install the latest lp spooler cumulative patch.

The load of the cpu in % is
relative not absolute.
If your cpu is doing nothing (no big application), 98% means low load.
