[Xymon] Issues after upgrade from 4.2.3 to 4.3.5

You should not have ghost clients. If you do, the host and the client
are not seeing eye to eye about what to call the machine. Sometimes this
happens where the client provides the short name and you've entered the
long one. I believe a CLIENT= statement on the line is what fixes that.
I don't know if that helps -- your e-mail is a little unlclear altogether.
