The presence of lines in the .cm.log file on a network server containing the statement "Return Code 684" do not indicate an error condition.

Following a new release of the .cm file, the network server will update itself on its next connection to the CopyMinder servers. Then, as each client connects to it, it will tell them that there is a new version of the .cm file available so they can request it. It signals this by sending them a status value of 684, and records into the log that this has been done. This log file entry is only informational and will appear one for each network client until they are all transitioned to the version that matches the one on the network server.
