LPSHUT not working

[Nair1980]

when i am giving an lpshut .. it is not stoppiing my lpscheduler .. any idea ..

so I am not able to start it agian
and all print jobs are blocked

thanks in advance

[Tim Nelson]

have you looked for any child processes from lpsched ?

Have you tried kill -17, kill -15, kill -11 or eventually kill -9 ?

My first assumption is that it is stuck attempting to process a job to somewhere that is not responding.

i tried kill -9 lpsched

[Bill Hassell]

I am assuming you meant:

kill -9 ####

where #### is the process ID of the lpsched processes. If you typed kill -9 lpsched then you got an error message because kill never works with a name. You need to find *all* the lp processes like this:

ps -u lp

Then issue a simple kill signal to each process ID (PID) number. You can put all the PIDs on one line:

kill -15 123 1234 12345 22 33

then repeat the command changing the kill level to -1, then -9. Now repeat the ps -u lp command. All the processes that cannot be killed with -9 are waiting on I/O, very probably network I/O. In that case, you'll have to reboot. All unfinished jobs will be reprinted when you boot up.

Shall I kill all this process with the method above mentioned , will it make any problem (as this list contains some rlp process)

once it is killed what to do ?

Shall i restart the lp from /sbin/init.d/lp stop & lp start

> Shall I kill all this process with the method above mentioned , will it make any problem (as this list contains some rlp process)

Yes, you need to kill all the processes. Obviously, a lot of lp processes are running but they are ignoring the lpshut request. Since lp is not working properly, you'll have to shutdown everything that is owned by lp.

> once it is killed what to do ?

Almost always, lp problems like this are caused by network failures. You'll need to fix the network issues. If you do not have good network administrators to help find the problems, you can disable *ALL* the printers after killing all the lp processes. Then enable one printer at a time and look for a problem.

> Shall i restart the lp from /sbin/init.d/lp stop & lp start

The lp start/stop script just issues an lpshut (which doesn't work) and lpsched. I would also get your system patched to within 6 months of current bundles.

Nair,

It is a general issue of lp daemon.

I see your ps output show a lot of lpsched daemon, please kill -9 those lpsched daemons and make sure no more daemon running for lpsched.

Also make sure you update lpspooler patch as it fixed number of known issues
