I had a strange problem with a Arduino and Ethernet shield. My sketch uploads data to pachube.com. It was running fine for several days, then stopped uploading to pachube. I unplugged power from the arduino and it didn't fix the problem. I did this several times. Then I plugged the arduino into my laptop and ran the serial monitor. As soon as I got the serial monitor going, it started to successfully upload to pachube.com again. Now it's fine (for the time being). Any idea what's going on?

- could be some weakness with your code, 2) could be something to do with pachube.com, or 3) other. Not a lot of info to work with.

Since opening the Serial Montior causes your Arduino to reset, this suggests a problem in your code.
Removing power resets the Arduino also, so I don't see how that can be it. I'm wondering if starting the serial monitor does something different then just powering down, then back up again.

see below for a difference.
