Here is a series showing utime and stime for kontact over 2 minutes. Values were obtained using (identical values removed): $ while true; do awk '{print $14" "$15}' /proc/5269/stat; sleep 1; done | ts Oct 03 21:17:12 12220 1593 Oct 03 21:17:18 12221 1594 Oct 03 21:17:26 12222 1593 <-- Oct 03 21:17:34 12223 1594 Oct 03 21:17:43 12224 1594 Oct 03 21:17:51 12224 1595 Oct 03 21:17:59 12225 1596 Oct 03 21:18:07 12226 1595 <-- Oct 03 21:18:15 12227 1596 Oct 03 21:18:18 12228 1596 Oct 03 21:18:22 12229 1595 <-- Oct 03 21:18:31 12230 1596 Oct 03 21:18:39 12230 1597 Oct 03 21:18:44 12231 1597 Oct 03 21:18:48 12232 1596 <-- Oct 03 21:18:56 12233 1597 Oct 03 21:19:04 12234 1596 <-- Oct 03 21:19:11 12235 1597 So, is it normal that stime decreases sometimes or a kernel bug? /me expects the last... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
