on some boxes we can see a high load, but i have
no idea, what the cause of this:
Mem: 27740K used, 1264K free, 0K shrd, 2160K buff, 9592K cached
CPU: 0% usr 0% sys 0% nic 97% idle 0% io 0% irq 1% sirq
Load average: 1.03 1.02 1.05 1/40 9974
PID PPID USER STAT VSZ %VSZ %CPU
There is one process/thread that is in a block state but uses no CPU. I got
similar behavior with a blocked syscall waiting for a SAN lun disk recover.
Probably your process has a blocked syscall. Is there any kernel oops dmesg?
Try to kill the remaining process. A blocked process will not die
Second look. Check if khubd keeps state D (uninterruptible sleep). Maybe a
USB device caused it.

thank you 'Luiz Angelo Daros de Luca',
the reason was khubd / a USB-issue. i did nothing, just waited
and it was repaired automatically. according to dmesg, there
was something USB-related, but without user-action:
Ahh, recentlly I deployed Barrier Breaker on a friend's exactlly same
router model and he has said it was getting very similar behavior (high
loads without any apparently reason). We tried to revert back to AA
which I am not sure if clear the issues (I guess it would if it's a
kernel issue).
