I installed the R1A4 RC (hrevr1alpha4-44576) on my beefy laptop with

It sounds like swap is double the ram by default... but on these
8-16GB systems, the swap file grows larger then the available free
space causing issues.
Confirmed...

Is there a swap setting?
Init it.
Does the swap setting not exist?
size = (off_t)vm_page_num_pages() * B_PAGE_SIZE * 2;
There are several issues with this:
* The swap space can be very large without taking into account the
filesystem size
* The automatically chosen size is never written anywhere so the swap
preference panel
isn't aware of it.
I'm seeing if there is a logical way to fix this without breaking
anything :)
