Right now we are connected to about 20 devices and the tag count used is small.
The main gateway is pointed at an installation of Panel Edition.
This was done to give developers the ability to add or remove devices. They have admin rights on this machine, but do not have admin rights on the main gateway.
This is a workaround, because there is not enough granularity in the permissions system.
It does work! The main gateway is running on 64 bit CentOS Linux and the Panel Edition is running on Windows Server 2008 R1 (32 bit). All of this is running in VMware Enterprise.
The JVM on the Panel Edition is taking about 1 gig of ram and I was trying to cut that down.
