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. Dr. Steven M.
