Sorry, i forgot to mention that there is a link:
/data -> /mnt/xxx/
which point to the HD.

The measured maximum recorded rate is ~23 fps. My very first try was recording
one picture in every 15 second, which is very slow, and it also leaded to
crash in 3 days. Faster recording crashes sooner.
------------------
I checked some out-of-memory situations, and found strange things. You can
easily try it (i would like to hear if it works on your system or not): create
a big directory (~50k...100k files) and give a simple 'ls' command:
$ ls /my/big/directory
No swap is in use, my physical memory is 32M.
The 'ls' allocates very much memory, which leads to out-of-memory. AFAIK, the
kernel calls the oom-killer, which should kill the biggest process ('ls' in
this case). It happens, but the system hangs. Some seconds later the following
message appears on the console:
bcm47xx_wdtWatchdog will fire soon!!!
This is the very last message, the system does not respond any more.
I think this situation should be handled correctly.
Thanx
K. Gy.
