I'm afraid there isn't enough information here to let us debug the issue. Your gdb attach seems to have failed. If you can reproduce the issue, please do the following: 1.

Once the problem occurs, save the console output and enter it here 4. If discover crashes or hangs, get a backtrace by typing `bt` in the gdb command line and entering the output here
