It would help if you could find out which particular thread is using that CPU percentage. You can do ps -T u -C vdr to get a display like USER PID SPID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND kls 27146 27146 3.7 5.8 124132 22568 pts/0 Sl+ 10:49 0:08 ./vdr kls 27146 27150 0.0 5.8 124132 22568 pts/0 Sl+ 10:49 0:00 ./vdr kls 27146 27151 0.0 5.8 124132 22568 pts/0 Sl+ 10:49 0:00 ./vdr kls 27146 27152 1.6 5.8 124132 22568 pts/0 RNl+ 10:49 0:03 ./vdr kls 27146 27154 0.0 5.8 124132 22568 pts/0 Sl+ 10:49 0:00 ./vdr where the SPID number corresponds to the thread's "tid" number in VDR's log entries, as in Jan 3 10:49:19 video vdr: [27152] section handler thread started (pid=27146, tid=27152) Klaus _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
