FLEXnet limitation with many distributed servers

This might be useful for others with many distributed FLEXnet license servers.

Chris Dodge at Microdesk shared the following with me:

Just ran across something interesting with a large client -  Have you heard of this?

They had recently been having a problem where their "Suite" Autodesk products like Land Desktop companion and some of the Revit products could not get a license.    But "Regular" products such as Civil 3D 2008 and Acad MEP had no trouble.

Of course I checked and double checked PLIST – All was fine.

It WORKS if we set FLEXLM_LICENSE_FILE (registry and environment) to a SINGLE server.

The customer finally figured out that the problem started happening when they added a few more FLEXLM servers in the company….

They have a total of 17 servers – He counted the number of characters in his "@server1;@server2…" string, and found that products that need to "CASCADE" for their license don’t seem to like a server list that is over 128 characters.

PS. JTB FlexReport has no limitations on the amount of servers it can report license statistics on.
