[arch-general] cpu usage very high after update...
My cpu monitor is almost reading 100%, right after I updated today. It was a very large update because I hadn't updated in about a month.

What got updated? A lot, :-). I know KDE 4.2 -> 4.2.1. I searched the forum and wiki but could not figure out what file or command to pull up or use to show you what got updated?

A quick google gave me this : https://bugs.kde.org/show_bug.cgi?id=155904 The cpu usage mentioned are not anywhere near 99 though, but still worth a try to add this to $HOME/.kde4/share/config/kdedrc: [DirWatch] PollInterval=60000 Otherwise, a general tip is to try with a fresh new user, to find out whether it is indeed a configuration problem.
Thanks for the replies. Bram, I did install KDE and I did restart after updating, although this is the first time I have logged into KDE since the update.. Xavier, that is interesting. It seems to be a problem with KDE 4.2, surely they would have fixed it with KDE 4.2.1? I never have had this problem before when I was using KDE 4.2. In short my CPU usage will not go below around 50% and keeps jumping up to 95%-100% a lot of the time.
Hello Preston,
I have had this problem on occassion, but it only appears maybe 3 times. I do a killall kded4 and then krunner -> kded4. That seems to calm it down. I do not understand what it does exactly.

I posted on the KDE forum, so I will see if they have any tips, before I try to do to much.
Interestingly, I rebooted again, this time not immediately after the update/upgrade, but after logging into KDE. Everything seems to be fine now, hopefully this problem will not come up again. Thanks for the help.

If you have problems again do a strace of the kded4 process, this process normaly do a poll() of some sockets and pipes. Also if appears again ensure that have a clean /tmp and /var/tmp/ ;) For example, in normal execution, the poll interval is 5 seconds ( see http://djgera.pastebin.com/f6c2ca1bc ) -- Gerardo Exequiel Pozzi ( djgera ) http://www.djgera.com.ar KeyID: 0x1B8C330D Key fingerprint = 0CAA D5D4 CD85 4434 A219 76ED 39AB 221B 1B8C 330D

http://websvn.kde.org/*checkout*/tags/KDE/4.2.1/kdelibs/kded/README.kded says that this option is now stored in kdeglobals. Anyway if the fam daemon is active it isn't taken in account.

Did you restart X/KDE after updating? I bet this was among those updates. Kind regards, -- Bram Schoenmakers What is mind? No matter. What is matter? Never mind. (Punch, 1855)
