Performing the check at the time the network configuration changes will
guarantee that the cache manager talks to a large number of servers
(normally, every server it has ever had a reference to since starting)
many of which the user may not care about.
It seems the simplest thing to do here is whenever an interface is
brought up to reset the state of all servers to "up". This results in a
fast response time for a server that really is up, at the expense of an
extra timeout in cases where the user touches a server that is down
before the CM gets around to doing the next 5 minute check.
the CM is going to send the UP probe to every server the client has ever
communicated with once the 5 minute check comes around so there is no
point putting it off. Just make sure that you reset the 5 minute check
timer when you do it.
Updating the UNIX CM to use multi_VL_ProbeServer instead of
probing each VL server in serial would be a win.
