Description illumilore 2011-05-18 02:14:45 UTC 
Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

Whenever running a program that goes amok, ie starts using %100 cpu or hard drive, kde will eventually lockup.
Example of this would be running an fullscreen game inside virtualbox, and then constantly resizing virtualbox until it starts locking up. When this happens, kde will freeze up with it, after a while, ctrl-alt-f1 does not even work.

KDE should launch programs at a lower priority or set critical system and UI priorities higher so that this does not occur.

Reproducible: Always

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!

Dear Bug Submitter,

This is a reminder that this bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? This bug will be moved back to REPORTED Status for manual review later, which may take a while. If you are able to, please lend us a hand.

Thank you for helping us make KDE software even better for everyone!

No response; assuming it was fixed since then. FWIW this is currently being worked on in a generic sense with systemd slices and cgroups, which should be released in Plasma 5.21.
