This is the exception which I am getting. The server gets shut down but it might affect indirectly. When I restart the server from admin Panel it does stop but doesn't start. I am using Smart Fox Server 1.6.8 for Linux. Please help me out to debug this exception

I had already seen that and my issue is that I am not able to restart my server using admin panel. Please let me know how to solve that. When I click on server restart button the server stops but never start. Please let me know about this...

Thanks,
Gaurav

What you need is a "hard" restart instead of a soft one.
The restart performed from the Admin panel doesn't shut down the JVM and it can at times fail to clean up all the resources.

A "hard" restart is done by restarting the service. Under Windows you do it via the Service Console, under Linux you do it from terminal by issuing a sfs restart command
