testng: Getting Unreachable browser exception after a while when I am running the TestNG tests. OS : MAC

I am running my tests in MAC as well as in Windows. In windows, the code works like a charm. In MAC OSX, I run the same code and it will be working fine BUT after a while I get unreachable browser exception. I am running my test through maven surefire plugin. maven version : 3.3.9 surefire plugin : 2.19.1 testng version : 6.9.10 java.version: 1.8.0_77

Here is my stacktrace

Again, reminding you that the tests work perfectly fine windows machine. OSX version : 10.11.4 . I hope I can get a fix for this.

Also, Right clicking the testng.xml and clicking on run as testng suite IS WORKING FINE.
