Thanks for the tip Seth.. That appears to work, thanks! I reached out to Rob and he pointed out that, when using tmpfs, the fs will fill up at 50% memory usage, so the ENOSPC is to be expected here. Now that the cause is known, I think we can get away with bumping the default and minimum required memory to 1GB for our ramdisks and we should be okay across the different kernel versions / rootfstypes.
