…because i was desperately fighting with my pimatic/raspberry, both was always badly crashing without any reasons.
what i tried is to move the entire installation from my hard drive to another hard drive => no changes
also i replaced my power supplier from a 2A to a 3A => no changes.
1 week ago i finally found the solution: it was so simple that i forget to check it.
My raspberry pi 2 was overclocked (using raspberry-config), what i did is to simple revert it to original speed and since then it works rock solid.
So if you have crashes don’t forget to switch you rasp to its original speed and see if it’s improve the situation…
Cheers
