cups demon takes all available CPU time #35

Closed michaelrsweet closed 21 years ago

michaelrsweet commented 21 years ago

Version: 1.1.19rc2 CUPS.org User: meyerv.winflex

Installed cups 1.1.19rc2, packaged from Mandrake Cooker as 1.1.19-0.6mdk. On restarting, the demon takes all available cpu time. Restarting the demon shows the same behavior.

Please try compiling the standard CUPS distribution and let us know if the problem persists - Mandrake includes many patches to the CUPS software in its RPMs and it is likely that one of them is causing the problem.

(Also, it might help to send a bug report to the Mandrake folks, specifically to till.kamppeter@gmx.net who does the CUPS packaging for Mandrake...)

CUPS.org User: till.kamppeter

There are no patches in the Mandrake package which affect the behaviour of the scheduler running in the background. Most are patches on documentation and configuration files. The only code patch on the scheduler hooks into the authentication and as the scheduler is not authenticating all the time when it is running, this patch should not cause the high CPU consumption.

What is your exact configuration? Post the output of

grep -v "^#" /etc/cups/cupsd.conf | grep -v "^$"

How many printers have you installed? Which ones? Post

lpstat -t ls -l /etc/cups/ppd/ for i in /etc/cups/ppd/.ppd; do echo "$i:"; head -n 40 $i ; done for i in /etc/cups/lpoptions /home//.lpoptions ; do cat $i; done cat /etc/cups/printers.conf cat /etc/hosts ls -l /var/spool/cups ls -l /var/spool/cups/tmp

Then let's see if your configuration isn't causing a problem...

Cheers, Kurt

In addition, it would be helpful for you to attach a copy of the /var/log/cups/error_log file and run the command "strace -t -p -o strace.out" when the cupsd process is consuming 100% CPU and then attach the strace.out file.

Kurt, here's more of the info you asked for. I'm not too sure that the smb connections are correct. Neither of them actually works, although they were configured with the cups web tool or with kups. The network workgroup name is "familydoctors", the front desk with the laser printer is "front". There is an HP4 on a linux server running cups named "server" [root@localhost meyerv]# lpstat -t scheduler is running system default destination: Samsung device for Samsung: smb://FAMILYDOCTORS/FRONT/ML-1450 device for test: smb://front/ml-1450 Samsung accepting requests since Jan 01 00:00 test accepting requests since Jan 01 00:00 printer Samsung now printing Samsung-6. enabled since Jan 01 00:00 printer test now printing test-7. enabled since Jan 01 00:00 Samsung-6 meyerv 15360 Fri 14 Mar 2003 03:34:43 PM EST test-7 947200 Fri 14 Mar 2003 05:30:36 PM EST

and just keeps repeating the same ad infiniteum.

OK - there were two jobs pending. When I put the printer these jobs are for on hold (ie, not accepting new documents) and reboot, problem goes away. The error log makes it look like it never stops trying to reach these printers - even though it says it's going to wait 60 seconds.

Timing on pending jobs maybe related to the problem?

michaelrsweet commented 21 years ago

CUPS.org User: mike

What version of SAMBA are you using? Older versions of SAMBA included a smbspool program that didn't retry at the specified interval.

michaelrsweet commented 21 years ago

CUPS.org User: mike

OK, never mind, I have duplicated the problem without the SAMBA queue - there is a missing FD_CLR somewhere in the code.

Should have a fix for this today (also affects 1.1.19rc3)

michaelrsweet commented 21 years ago

CUPS.org User: mike

The attached patch should fix the problem and is included in CVS for the next release candidate.

Please let me know if this doesn't fix the problem for you and I'll reopen the STR.

michaelrsweet commented 21 years ago

CUPS.org User: meyerv.winflex

Thanks! I'll wait for the Mandrake Cooker package of RC4 and will re-test.
