org.openqa.selenium.remote.UnreachableBrowserException

[manasa priya]

Hi Guys,

I am a newbie to selenium and webdriver. But working with selenium 2.37.0, trying to run selenium tests.
Surprisingly, selenium tests which run perfectly fine in Ubuntu/Selenium 2.37/Firefox 25.0.1, fail in the very same environment, but in mac OS.

The stacktrace is as given below. Found many links reporting a similar issue, but no solutions to it.
Any tips/suggestions as to how to get rid of this exception is greatly appreciated.

org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.
