Android Emulator getting disconnected middle of the test execution

Hi All,

I was runing testing scripts on emulator from remote machine, but it is getting disconnected middle of the test scripts ( total 80, passed:23 skips:57) and getting error "org.openqa.selenium.remote.SessionNotFoundException: " and some times "Caused by: org.apache.http.conn.HttpHostConnectException: Connect to ip:4723 " both machines are same domain and network, but local machine (VM) and remote machine (real machine).

How to handle this issues, i am accessing android emulator on remote machine.
Thanks for advance helping to solve this issue.
