pfSense isn't using ZFS so I'm going to go with no. Those are pretty standard messages though. ZFS runs like crap on anything less than 4GB of RAM.
ZFS can be used if you monkey with the web-based installer (go to /installer/ when booted from the CD) but if you didn't manually go out of your way to set it up, it won't be used.

I have also noticed the ZFS memory warnings and wanted to ask if the new 2.1-RC0 kernel has a larger memory footprint compared to a v2.1 kernel from a few months before.
I'm asking because a 256MB VM running the latest 2.1-i386 image with no packages installed, on a quiet network (only 17 states) consumes about 45% of memory, according to the Dashboard info …
