Node freezing up

@ferpando You can enable a watchdog timer on your Arduino. If your code hangs your Arduino, it should reset/reboot it. But not sure that would reset the radio.

I have exactly the same Problem. But I'm not sure the relays are the problem.
I've added a keep alive message to know when it stops working and implemented a watchdog.
That sounds like you keep the motor running and accept that the car crashes every once in a while Better to find the root cause of the "freeze" and eliminate it.
@AWI You're right of course! But ... if the Arduino is the root of all evil in this case, it will reset once in a while but still work. If it still freezes it could be the radio that crashes. So I'm still trying to solve the problem.
All parts use the same 5V source (which I already switched) but the radio of course is connected through a regulator. If the watchdog solves the problem (so the radio is not the problem) I will add a bigger capacitor which I already ordered.
I made this regulator based on this schematic to power the node independently, to see if it solves the problem.
Does this node by any chance have a temp. sensor also?
My nightmare.. http://forum.mysensors.org/topic/338/reliability/3
Mine doesn`t at the moment, but should be easy to add.

Any update on this?
Asking since I also have a multisensor that locks up every now and then. Thinking of some way to reset the radio a couple of times per day.
Any suggestions how to implement this?
No more node lock-ups since I installed that power supply, so it works as expected.
