Re: [opensuse-factory] Factory Snapshot 20141001, KDE hangs while copying big files
Hi again, i see very high i/o waiting while the problem happens (~90%), and i think its this Problem https://lwn.net/Articles/572911/, after setting vm.dirty_background_ratio = 1 (default 10) vm.dirty_ratio = 5 (default 20) the problem does not occour, and the i/o wait is only about ~50%. So KDE does something which calls sync, maybe the indexing? regards Florian 2014-10-04 21:22 GMT+02:00 Florian Koch <florian.koch1981@gmail.com>:
hm, if its a Kernel Bug it should happen also with Gnome

I think it's partly a hardware issue. The copy is hogging the bus or the interrupt handler or something.
Sounds like a kernel bug.

Try shutting down firefox Has happened before: https://bugzilla.mozilla.org/show_bug.cgi?id=421482 And it seems to be happening again.

It is a bug in KDE, sockets are stored on /tmp which is the same partition as they copied file, so they block each other. There is a patch to move it to XDG_RUNTIME_DIR which is in ram by default in OpenSUSE: https://git.reviewboard.kde.org/r/120492/ On 7 October 2014 03:54, Claudio Freire <klaussfreire@gmail.com> wrote:

FTFY. Notice that my instance of this issue did not involve tmp, to my knowledge, but /home. Not sure if that socket thing still applies when home is the one being stressed? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
