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
vm.overcommit_memory = 2
vm.overcommit_ratio = 200
after adding those lines of code run
to activate the new code.
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.
