This is a reply to a message from about a year ago (pasted below). I ran into this error message on a system with RHEL 3.0 (2.4.21-27.0.1.ELsmp #1 SMP Mon Dec 20 18:47:45 EST 2004 i686 i686 i386 GNU/Linux)
The dx that gave this error was 4.3.2 compiled on a Fedora Core 1 machine (with --enable-shared --disable-static, but this probably does not matter. Also, on both machines the Red Hat 9.0 rpms of OpenDX 4.3.2 work fine.) Anyway, the error message goes away when I pre-pass DXSHMEM=1 to the /usr/local/bin/dx script. May have something to do with the SMP kernel.

I still can't get DX to run with more than 930 MB of RAM. I know that the stock answer is to reduce the amount of data that DX is working with but I don't think that is an option for what I want to do. The setup of this machine is: Opteron 148 CPU 2 GB of RAM 4 GB of swap space Redhat Enterprise Linux Workstation (x86_64) release 3 OpenDX 4.3.2 installed using the opendx-4.3.2-1.rh9.rpm Maybe this is a limitation of how this version was compiled. If I compile the source myself is there an option for setting the amount of memory that can be used? Thanks for your help.
