KDE applications starts to stall after some (unknown) time

Hello fellow Arch users.
  I'm struggling with a very weird problem and I do not know where should I look to solve it. Now to the core. When I'm using my laptop some KDE applications like Dolphin, plasma-desktop... begin react really slow. For example start takes about one minute, when I press right mouse button to show context menu, it took as well about a minute. I've compared strace output when the application runs correctly and when it begin react as I've described but they are almost the same and I do not see any error, however, during the mentioned problems the strace always stalls on "EAGAIN resource temorarily unavailable" and the resource is /tmp/.X11-unix/X0 or /tmp/dbus-*, which by the way do not exist. Not sure what could cause this behavior. Have anyone encountered with these problems or have anyone some advice where I should start the search for cause.

P.S. Excuse my errors in English, I'm not native speaker.

Re: KDE applications starts to stall after some (unknown) time

What have you done to diagnose the problem (actual commands and output, not "I ran 'such and such', I saw nothing")? What do your logs say (actual output, not "logs said something about 'such and such'")? Do you have htop installed? Is there something eating the processor? What's running in the background when it starts to lag? Cron jobs? Systemd timers? How full are your harddrives?

Re: KDE applications starts to stall after some (unknown) time

hello Buddlespit,
  I've checked the dmesg output before and after the problem occurred and checked the outputs

dmesg | tail -n 50

But this showed me nothing weird.

Then I've checked the X.org log. There is only one line which is bothering me:

systemd-logind: failed to get session: PID 570 does not belong to any known session

however, this messeage occured always and before the problem.
Then, as I mentioned before, I ran the strace to check output, which lead me to idea of re-install xorg. I can provide those files later, right now I'm not by the "failing" computer.

To htop: I do have htop and I've checked the usage, but it was actually very low. Also application like VLC, mplayer, konsole, chromium were running pretty smooth.

To systemd timers: how could I get information about them?

To harddrives: each partition has more than 50% of free space.

I might to upload also result of journalctl -xe if you want to.

P.S. as I'm thinking about the problem, I saw few times baloo_file running 100% cpu before, maybe it has something to do with my problems, however, I haven't noticed the baloo_file process was running during the problems.
