FLEXLM_DIAGNOSTICS is an environment variable that causes the application to produce diagnostic information when a checkout is denied. Set it to a value of
3 to obtain the most information.
FLEXLM_DIAGNOSTICS = 3
On UNIX, the diagnostic output is sent to STDERR.
On Windows, the diagnostic output is sent to a pop-up window (see the example below) and, if the application is run from a command prompt, a file called flexpid.log (where pid is the application’s process ID). The file is found in the current directory.
