Title: Message
We are having severe problems with the EPICS gateway, and I'm hoping that someone can help us resolve them.
 
The problem is that the gateway is continually crashing whenever we open up a GUI display with requires connection to multiple IOCs.  These are Libera BPM boxes, and we have 98 of them.  We have a status display which shows the status of 33 of these at once.  As we scroll from one display to the other, the gateway invariably crashes.
 
(This is a gateway between our office network and our accelerator network, and is used for monitoring the status of the machine from our desktops.)
 
The gateway log provides the following information:

Has anyone else seen the memory problems that we are experiencing?  Is this an indication that we are trying to connect to too many PVs at once?  Will purchasing more memory for the gateway perhaps alleviate the problem.  It currently has 512MB but we are planning to upgrade it to 1 GB.
