When you get “JavaScript runtime is out of memory; server shutting down instance” errors in your FMS logs, and your app won’t stay loaded, and none of your clients can connect, you need to increase the amount of memory available to the script engine.
In the docs for FMS 4.0, the JSEngine tag is “deprecated”. This means that when your app runs out of the default 1024K, and you try to crank it up to 51200, it’s actually not changing anything. In FMS4.0, you have to change the xml tag, in Application.xml, to ScriptEngine, increase the setting, and restart fms, to fix this.
