This morning I was working away got into a groove and then I got the error:

Code: [Select]
RXTX Warning:  Removing stale lock file.

Now I can't communicate with the mega from eclipse on my mac.  I can still connect via the arduino serial monitor (not at the same time of course).

I did some googleing but couldn't find any solutions.

Any suggestions?

Edit:  my java app will not communicate with my uno either.


This started happening to me too out of the blue (was workinf fine before). The only solution for me was to run the arduino IDE from the terminal using sudo. Did you find any other solutions?
