During a strong file I/O application, the Pi regular crashes.

using Raspbian "wheezy" 2013-02-09-wheezy-raspbian.zip (and updated)
Different Raspberry Pis and different SD-Cards (same series) cause the same problem. I test other cards in a few days. I remember a different card (class 6 instead 10) would have held out for a week already.
memtest 480 2 is okay Measured Voltage on TP1 and TP2: 4.87V Tried with and without USB-Hub with a power supply.
Is there a way to tell the watchdog, the system (mmc0) crashed?
A dirty hourly cron execute /sbin/init 6 does not work in this case. Reverse ssh neither.
I know I am not alone with this problem: http://elinux.org/RPi_SD_cards But I can't test hundred cards.
I want to play it safe and fix it automatically if need (restart is a acceptable solution for me).
By the way: Restart the Pi every hour just delay the problem. Sometimes it occurs after 2 minutes.
Thank you for any help. Kind regards from Berlin
