https://bugzilla.novell.com/show_bug.cgi?id=807513 https://bugzilla.novell.com/show_bug.cgi?id=807513#c1 --- Comment #1 from Jean Delvare 2013-03-05 14:31:32 UTC --- After quitting gpk-update-viewer, I ran it again from a terminal, and this time it worked just fine (did not ask for a password.) So it may be a random bug that doesn't happen all the time, or maybe the difference is between starting gpk-update-viewer from the notification area vs. from a terminal. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

However an investigation of /var/log/pk_backend_zypp-1 suggests it wasn't so busy. For today, activity was recorded from 14:41:35 to 14:44:11, and then from 14:55:18 to 14:55:50. This would correspond to my first attempt, and doesn't correlate with the 30 minutes of CPU business. The second (successful) attempt is recoded from 15:29:42 to 15:30:27. I can share the file is you want, but it's large (11 MB.) Even limiting to today's messages results in a 1.6 MB file. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Check the output of: pkmon (packagekit monitor)

Transactions: [none] daemon connected=0 daemon connected=1 network status=online daemon connected=0 And nothing more.

Those should reveal activity...

Can you confirm this?

This would confirm that the issue is purely graphical and not related to package management at all. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=807513 https://bugzilla.novell.com/show_bug.cgi?id=807513#c11 --- Comment #11 from Jean Delvare 2013-06-21 07:40:08 UTC --- Additional information, which I think is valuable for reproducing the issue... Today I have checked the CPU usage with "top" on a 12.3 machine where the problem supposedly never happens. I noticed that gpk-update-viewer used about 50% of one logical CPU, while the actual update was using 100% of another logical CPU. This is a powerful machine, so from a usability perspective everything was fine. The machine I mentioned in comment #10 where the problem always happens, is an old laptop, with single logical CPU (single core and no hyper-threading). If refreshing the graphical interface has higher priority than doing the actual update, that would explain why on that machine the update never completes. So I suspect that the bug is happening on a lot more machines than we thought, but on most of them its effect goes unnoticed. If anyone wants to reproduce this bug, I suggest doing so on a machine with a single logical CPU (either a virtual machine, or a physical machine booted with maxcpus=1.) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You can download it at: https://build.opensuse.org/package/show/home:jdelvare:branches:openSUSE:12.3... On one machine it seems to help a bit with CPU consumption, but on the other one (the smallest one, only 256 MB of RAM at the moment) it did not seem to make any difference. So I can only guess there are two different bugs whose symptoms are roughly similar. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
