One error that we are finding is vboxwebsrv is failing and the VBoxSVC 
seems to take over the 18083 port.

netstat -anp | grep 180
tcp        0      0 * LISTEN      

We have to kill that process before we can restart vboxwebsrv.

I am not sure what is causing this, because it has been stable for us 
for a few years now.

This is on the 4.2.X series.

We are going to upgrade to 4.3.X to see if it resolves the issue.

Also another note, this is only happening on a single server.  Other 
servers seem to be running OK.

Happy Holidays!!
