Short of editing `/usr/local/WowzaStreamingEngine/manager/bin/startmgr.sh`, is there a way to set the max heap size for the manager, as opposed to the streaming engine? It seems like it always uses the JVM default of 25% hardware memory size, and that this is not configurable. ---

In Wowza Streaming Engine Manager, you can specify a maximum of 10000 MB, which should be sufficient for most streaming needs. To do this, you will need to edit the [Wowza-Install]/conf/Tune.xml file using a text editor. ---

@Cassidy_Reilly That’s the heap size for the streaming engine, but what about the manager itself, which runs as a separate process?
