I have installed the lastest KDE Version (4.7.1) on arch linux,
but strigi is killing my system. After 2 hours uptime,
I have a 32GB .xsessions-error log with always the same error message:

nepomuk GLib-WARNING **: poll(2) failed due to: invalid argument


I don't know whats wrong here...

not a solution - if you open kdebugdialog and search for "strigi" and then deselect those found the error messages should stop populating .xsession-errors

Well... I have disabled the logging for nepomuk now.
But I also would like to know... how to solve the problem,
otherwise I can't use the desktop search

you could trying asking on freenode irc channel #nepomuk-kde or mailinglist http://lists.semanticdesktop.org/mailma ... epomuk-kde
