During restart, ProcessManager sometimes generates a warning

During restart or shutdown, every now and then the ProcessManager will log a warning:

Client read close socket for InetStreamSocket::readToMagic: Remote is closed

This is most likely caused be a timing of when the shutdown occurs and whether there may be an open socket waiting for a message. It doesn't seem to cause any issues, but it sure is annoying and looks bad to the customer.

It is possible this is being generated during the start phase, rather than the stop phase.
