Node Server Process Ended

Hi,

Am currently working on appium 1.1.0.0 for mobile automation using with genymotion v:2.2.2.
As far as i concerned am going good with appium, but now am facing this issue “Node Server Process Ended” while executing tests.

Am getting this issue in the middle of my test executions suddenly. Please help me out with this.

FYI: Am starting Appium through app by clicking launch button.Is there a way to start programmatically to start server.

Does it really resolve this error by launching the appium server through command line.

Regards
Phaneendra
