Hmm...that sounds like a power problem. How are you powering the servo? If it's running off the 5V regulator on the arduino, all kinds of bad things like you describe can happen.

On my RAMPS-equipped printers, I pull off the 5V power jumper, cut D1 and run two separate 5V power wires from the power supply to Vcc and +5V so they're powered separately. This has solved most of my servo twitching issues and commands that seem to abort or just not run intermittently.

You can also use servo deactivation to keep it from running at all when you're not probing.
