Jeff, How do you know the LDM is using the memory? On a Linux system, the operating-system will consume as much memory as it can without interfering with user processes.
For the first few years of running Linux, I had wondered the same thing.Look at your load average, for starters. If you're below 1, chances are it's all good. 12 GB of RAM is fine, and you'll never use that much. Bill Gates told me so! ;-)
I have found that running 1.2 GB queue out of /dev/shm for my LDM, even with level 2 data coming in, works fine. It is on my NOAAport ingest server, whose load average most of the time is flat out zero. It does jump up to about .50 when NOAAPort is closer to it's current 10 mb/sec max.
