Thx for the reply.

I agree that it can happen for hosts to be down, but why is it expected for 
hosts to be down?

IMHO one should be able to know which connections failed. (- Maybe it was just 
a typo in a config.)
 
Not knowing, makes debugging harder than it needs to be.

The current implementation gives me no way of knowing. I could place anything 
into the servers array and get away with it.

I think that one should be able to at least "trap" failed connections. 
In my case I depend on the connection being OK (and if not I must know about 
it ...)

Regards & thanx again,
