Hello Reuben,
We have a web application available via a URL of which Genero forms a part, so I would be monitoring "https://<url>/cefinance/wa/r/webappshtml5/<filename.xcf>" or similar pages, using say, a Web Service event monitor, that runs, say, every minute to check the page is accessible and as the page loads, it starts a session in Genero and because the monitor does not press the exit button like a user would do, it leaves the session open and next minute opens another session and each session holds down one user license for a period of time, the application gets killed very fast depending on how fast your web service monitor works.
Regards,
Ramu
