cupsd uses 100% CPU

[Šarūnas Burdulis]

cupsd constantly uses 100% of CPU (one core) when cups-browsed is running too. Network printer queues are autodetected and available. Printer listing is usually delayed by approx. 30s.

Status changed to 'Confirmed' because the bug affects multiple users.

[Chrescht (sekateur)]

For me nothing worked but to disable the cups-browsed service:
sudo systemctl disable cups-browsed

It disables the excessively active service to add any found network printers(!)

I have done several fixes in cups-browsed upstream to avoid high CPU load, infinite loops and crashes.

The fixes are in the 1.21.6 release:

https://github.com/OpenPrinting/cups-filters/releases/tag/release-1-21-6

This release should be available in Disco.

I think i'm hitting this bug too.

cups go CPU 100%, until i restart them.

Ubuntu Bionic, cups 2.2.7-1ubuntu2.3, cups-filters 1.20.2-0ubuntu3.

I can safely install disco packages on bionic? There will be some backports? Or some workaround for bionic.

Thanks.

I'm having this issue on Disco. Stopping cups-browsed solves the issue, restarting it makes the issue reappear after a few seconds.
I'm seeing this in the error log:

I can confirm that.

CUPS got 100% CPU in an environment where i've some KONICA-MINOLTA MFP, and i've the same errors in logs:

Note that i move my PC between at least 3 environment (home, work site 1, work site 2) with similar configuration, and only on 'site 1' (where i've KONICA-MINOLTA MFP i got 100% CPU.

[Corentin (jackylejacky)]

Same problem for me only on the local network of my work.

cupsd -l is using a 100% of one CPU.

"service cups restart" give me a little break but it restarts each time.
