ps -ef|grep -i lpsched

Is scheduler running??, If not start it and check log file.

lpsched -v
/var/adm/lp/log --> to check it.

hi,

remove the file /var/spool/lp/SCHEDLOCK if exist and then restart the lpsched

GOOD LUCK!!

In addition to removing the SCHEDLOCK, you may also want to remove the FIFO and CLD_FIFO files in /var/spool/lp as well. If this doesn't correct the issue, you may try opening another terminal window and tail the lp log file to see if a specific printer is causing the lpscheduler to stop automaically.
1) lpshut
2) rm /var/spool/lp/SCHEDLOCK (FIFO and CLD_FIFO if present)
3) open second terminal window and type
tail -f /var/adm/lp/log
4) in first terminal window type
lpsched -v

Micheal,
no file SCHEDLOCK at this path '/var/spool/lp' ..file FIFO & CLD_FIFO
also not exist

below are the log after do 'lpsched -v'

# tail -f /var/adm/lp/log
***** STOPPED Nov 25 11:47 *****
lpsched: can't open request directory request/psap14_ei/

But even I do 'lpsched' actually this scheduler not running ... look at this ..

# lpsched -v
scheduler is running

root@mke_DEV [/]
# lpstat -t |pg
scheduler is not running
no system default destination

printer psap14_ei is idle. enabled since Nov 24 11:06
fence priority : 0
printer SMMPR2134 is idle. enabled since Nov 24 11:24

no entries

root@mke_DEV [/]
#
... also look at this ...
# ps -ef |grep -i lpsched
root 22287 18892 1 12:25:39 pts/td 0:00 grep -i lpsched

root@mke_DEV [/]

no scheduler running ...

any hint ... does inetd and lpdaemon concerned ..?

thanks ...

Hi,

Check if the the "request" directory exist in /var/spool/lp and it is owned by "lp"

If not , do the needful and check if lpsched starts and shows correct status

Did you try to some changes in the printer configuration like removing printer etc. recently?

The mode on the directory /var/spool/lp/request is incorrect; it should be 655. The system may also have the maximum number of files open that are allowed at any one time. Also should be owned by lp:bin
