Hi,
At last i could create symbolic backtrace (attached).
The hardware is an Asus WL500GP-V2, a 160 Gb HD (on USB), a UVC webcam
(Logitech Quickcam Sphere).
The commandline is:
mjpg-streamer -i "input_uvc.so -f 25 -r 320x240 -l off" -o "output_file.so -r
/data/jpeg"
128Mb swap is used.
Some commands are executed immediately before crash (see the attached file),
the free memory and other things are shown.
I cannot imagine that all the memory got allocated within some seconds
(filling 128Mb space through USB takes some time). I assume that there is a
problem in the kernel instead.
Regards
K. Gy.
