I have a project that logs data from Arduino to a sqlite3 database on Linino: http://forum.arduino.cc/index.php?topic=227344.0
I have solved some issues with help from people here, but am now experiencing a recurring problem. I run a php script on Linino via a cronjob that runs every minute. This php script syncs data from the local sqlite3 database to a remote MySQL database for web access. The problem is that after about 12 hours (almost exactly on some occasions), but sometimes after 24 hours, the dbSync.php script no longer runs (the data doesn't make it to my webserver). In the meantime, it appears that the sqlite3 command run through the bridge still works. After I reset Linino I see that all the data during the time when the php script was not running was saved locally. After this reboot the script syncs all the missing data.
Furthermore, I can still see the Yun on my router, but cannot access it via HTTP config access or SSH. Any idea what might be going on here? It appears parts of Linino become non-functional, but that the OS is still running somehow (since it can execute shell commands via the bridge). I suspect I will get asked for the PHP script, which I will provide in the morning. In the meantime, any ideas? Since this is a remote application, are there any other suggestions on how I can try to communicate with/reset the Yun remotely?
