I have a project that uses a webUI to control and monitor the yun's sensors. The data displayed from the controller is being updated on the site page with zepto.js. I used the TemperatureWebPanel example project as a starting point. I'm sending text message alerts with runShellCommandAsynchronously() which runs a python script. This whole setup works ok for days or weeks at a time, but then the code on the mcu stops running. I can still access/use anything on the Linux side of things. Is there a log somewhere that could help me figure out why the mcu or bridge is failing? Is there a shell command to check that the mcu is still running?
first, which Arduino Yun are you using, arduino.cc or arduino.org.
2nd, which Linux are you using, OpenWRT or Linino?
ALso which version?
The answers to your question depend on those answers.
My gut feeling is that it is running out of space.
Are you using a flash drive or SD card with arduino/www in the root directory?
That would offload the Web files to the flash drive or SD card.
