> When starting up a locator has no knowledge of cache servers that might be in the distributed
system but it will process server-location requests from clients and return them incorrect
information until it receives load info from the servers.
> In one test I saw a locator be ejected from the distributed system.  When it auto-reconnected
some cache clients asked it for server locations and, though there were 6 cache servers available
the clients got this exception:

> ServerLocator has a readiness check but it is only testing to see if its DistributedSystem
instance variable has been initialized.  It ought to wait until it has received a server load
