Bug ID: 379521 Summary: Kscreenlocker takes a full minute until it is responsive Product: kscreenlocker Version: unspecified Platform: Archlinux Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: greeter Assignee: plasma-b...@kde.org Reporter: spa...@modanese.net CC: bhus...@gmail.com, mgraess...@kde.org Target Milestone: --- Created attachment 105347 --> https://bugs.kde.org/attachment.cgi?id=105347&action=edit GDB backtrace Version: 5.9.5 (latest on Arch Linux x86_64). After my PC is up and running for a few (4~5+) hours, kscreenlocker_greet takes a full minute until it is responsive and reacts to keyboard or mouse input. And yes, I've actually timed it; the standard deviation was +/- 2 seconds. During that minute, CPU usages spikes to 100% and reserved memory (in top) eventually exceeds 500 MB. I've also noticed memory usage increases every 5 seconds or so, and by 10-20 MB increments. When the program's responsive again, CPU returns to normal, while memory usage is reduced to around 400 MB. The problem happens independent of how kscreenlocker_greet is invoked: by locking the screen; letting it happen automatically because of inactivity; or even by running it from the terminal directly (with or without the '--testing' option; it doesn't matter). Sending a HUP signal to the process or using loginctl to unlock the session is a workaround, but very annoying. GDB backtrace (attached) indicates the program is stuck waiting for... something. Since the time kscreenlocker_greet is unresponsive is so precise, I suspect it's a timeout expiring which causes it to be responsive again. -- You are receiving this mail because: You are watching all bug changes.
