Disabled IDS yesterday and memory utilization dropped to 50% of the 8GB.

Left it on overnight, and this morning memory and swap were both over 85% consumed.

Restarted host discovery service for grins and memory dropped to 40% and is climbing back up, currently 50% memory and 30% swap.  System rarely used swap before now.

Memory got over 85%, swap over 85%, so I restarted IDS (I had reverted it yesterday using the command in the thread above) to see what that might do, but it never restarted and shortly after the network went down.

The console showed thousands of netstat_bind_fail errors, and I had to reboot it.  The messages were flying by, and I had to log in blind and press "Enter" a bunch of times to get the menu to flash on the screen as I didn't remember the menu number for reboot (it's 6), and then I had to guess whether it was "y" or "Y" or "Yes" to get it to reboot.

Back to 50% memory and 0% swap used, but climbing again.

I'll have to roll back if this keeps up.  For now I am keeping the web GUI off to see if that helps and I'm monitoring memory utilization with "top -asH".  I'm also not running IDS for now.

It started with 2048M free about 5 minutes ago, and it's down to 1922M in that time.
