lpsched running multiple processes

machaya chivaviro_2 — Sun, 12 Dec 2004 03:28:12 GMT

I am using hp 11.0 and all my printers have stopped printing. I have rebooted the server but did not help. I have checked on the scheduler and got these results. When one tries to print a job it runs multiple processes which should not happen. I have checked the permisions they are all ok. What could be the problem.
# lpshut
scheduler stopped
but does not stop it.
# ps -ef|grep lpsched
lp 1331 1 235 10:14:56 ? 0:18 /usr/sbin/lpsched
root 1691 1377 0 10:15:45 pts/tub 0:00 grep lpsched
# lp -dhelpdesk /etc/profile
request id is helpdesk-1774 (1 file)
# ps -ef|grep lpsched
lp 3505 1331 121 10:18:27 ? 0:02 /usr/sbin/lpsched

You have spooler control file corruption. First, use lpshut, then follow with pr -u to find all the lp processes (don't use grep):

ps -f -u lp

Then kill each of the processes manually. If new ones keep showing up, you'll have to disable spooling in the /etc/rc.config/lp file and then reboot. Then with the spooler shutdown, delete the printer br69oc with:

cancel br69oc -e
lpadmin -xbr69oc

Now check the printer is truly gone:

lpstat -v

If not, you may have to rebuild the printing subsystem by deleting every printer and starting over.

Once the problem printer is gone, start the spooler manually with the lpsched command. Then print a vary small file on one pr more printers. If all is well, add the problem printer back again.

Hi

You may need to remobe

/var/spool/lp/FIFO /var/spool/lp/SCHEDLOCK

to make it run again
