#32 XMPP Server fail

[Diogo Vilar]

The grid was running normally. Sometime after, all the workers failed and in the terminal was printed the following error:

[Diogo Vilar]

This error is generated when the XMPP Server is stopped. We did some tests, and the OurGrid components work well when the XMPP Server is restarted. After, this error message can be improved.
