Description Jonathan 2009-01-28 17:43:40 UTC

Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    Unlisted Binary Package

Strigi is still busy with the first run. If I choose to suspend Strigi (for being able to work on my computer) the cpu load still remains at 100%. `top` shows me that there is constantly 0.0% idle.

At the moment over 90% of the cpu load is used by one process of nepomukservices, sometimes the load is splitted on two different processes of nepomukservices and I've also seen that the load of all nepomukservices combined is below 10% but then the %iowait takes all remaining cpu load.

If I disable "Strigi Desktop File Indexer" or the whole "Nepomuk Semantic Desktop" in the System Settings the cpu load returns back to normal.

I can always reproduce this behavior.

Same problem here with gentoo packages, using KDE 4.2.
I also tried deleting all my nepomuk strigi related config files. But no difference.

Comment 2 Sebastian Trueg 2009-02-02 12:51:54 UTC

Strigi will check the file system for changes even if suspended. Nothing is indexed though.
This is a known issue that will be solved soon, hopefully even fr KDE 4.2.1

On a related note, 100% CPU usage by these processes severely hurts battery life when using the ondemand governor. Possibly completely disable indexing when in a powersave powerdevil profile?

Comment 4 Sebastian Trueg 2009-04-28 14:53:08 UTC

fixed in svn just now. Now if suspended, the service does really nothing.
