The Network License Manager is designed to support a redundant server configuration containing 3 servers. No larger or smaller number of servers is supported at this time. See the following excerpt from their FLEXnet User's Guide:
"Redundant servers are a set of 3 nodes designated to serve the same license file. The license file has 3 SERVER lines. lmgrd is started on all 3 nodes. One of the servers starts out as the master server and serves licenses. If the master goes down, another server takes over as master. Redundant servers require a quorum of 2 servers to be up, or no licenses are served."
