pfSense memory reporting

  • 772

I have a box onto which I just installed pfSense 2.1. The box has 16GB of RAM and is a quad-core processor (yeah, we're planning on doing some serious traffic and using a proxy filter with a lot of clients).

The BSD shell is reporting correctly that 16GB of RAM is installed:

dmesg | grep memory
real memory = 17179869184 (16384 MB)
avail memory = 2604027904 (2483 MB)

My assumption here is that BSD reports memory usage much the same way as other Unix systems - the machine has gone ahead and "reserved" almost 14GB of RAM, which is why only 2GB is reported as available.

The confusion:

On the pfSense dashboard, it's only reporting the Available Memory, beside "Memory Usage" in the System Information Widget:

Memory usage 10% of 2534 MB

This concerns me. I need pfSense to see all 16GB of RAM, so that I can give an appropriate amount to the proxy content filter (SquidGuard).

Is this something to worry about? Why or why not? If it is something to worry about, how do I fix it?

    The issue was a (very) silly mistake. I installed the 32bit version of pfSense, and not the 64bit version.

    Problem solved!
