OpenZFS on OS X

Noticed this recently filling up my console:

Code: Select all

9/19/16 7:46:10.000 PM kernel[0]: SPL: MMT background 80% real memory check, vm_page_free_wanted = 0, vm_page_free_count == 28160, periodic reaping
9/19/16 7:46:16.000 PM kernel[0]: SPL: reap thread, last reap 302 seconds ago
9/19/16 7:52:08.000 PM kernel[0]: SPL: MMT background 80% real memory check, vm_page_free_wanted = 0, vm_page_free_count == 2810, periodic reaping

I'm guessing it's O3X related, SPL = Solaris Porting Layer? Does anyone know what it means? Should I be worried? I haven't noticed any ill effects, but there's thousands of similar messages.

Please raise an issue in the openzfsonosx/ZFS issue database on github. The messages are nothing to worry about, the code is getting a bit chatty.

Yep, its the memory allocator letting you know what it is doing. They have been left in place since we don't feel we are done with the SPL memory allocation. You can safely ignore them, but we may ask for them if you experience some issue

You can also print them out, and fold it into a nifty origami hat.

I don't have a printer, or any paper. Shouldn't O3X include these things?
