I found a major memory issue with Debian on the JaguarBoard. When the 1gb of memory is used up or it is estimated that a program will need more memory than is available the system will crash and reboot. If anyone is having issues with Debian crashing try this.
I limited the amount of memory usage by adding the following lines of code to etc/sysctl.conf
This prevented the system from crashing and only crashed the process hogging the memory, it also raised the estimated amount of memory allowed to be 200% of what is available. Hopefully this helps someone during their diagnosis process. If you are still having issues with Debian crashing try using a 2.4a or higher power adapter or plug the power to usb adapter directly into a 2.4a computer usb port and test instead of using the 2a Power Adapter provided with the board.
