When using an network version of an Autodesk product, you may see this error: FLEXnet Licensing error:-125,147.
This error can be safely ignored!
This message is generated by going into the Lmtools Utility > Server Diags tab > Perform Diagnostics button.
Basically, the core funtionality of licensing is provided by Flexera. Autodesk has customized the licensing scheme by using a PACKAGE line in the license file. The Server Diag tab only knows core Flexera functionality (i.e. FEATURE, INCREMENT) and therefore will error out with these PACKAGE lines.
