I wrote a program on QNX6.4.1 to collect data from GPS and write it immediately into a txt file. I tested it for 1 or 2 hours, created a txt file about 6mb or more and closed the program. When I tried to open the txt file, the system turned off and keep rebooting. What I mean rebooting is that it started to reboot right before the log in window shew up.
We used a single core onboard computer but I usually booted up the system with default qnxbasesmp and it worked well before.
I turned off the power and wait for a while then booted the system with qnxbase and entered the system. After I opened the txt file and tried to drag the scroll bar to read the data the system turned off and kept rebooting again.
Do anybody know this kind of situation?
