I know this. But yesterday I noticed that the rise in ram continuation happens after it hits 100%, it then drops from 100, then rises again to 100, then the ram incremently rises abit. This continues until the ram is maxed and system instability. I have used zfs for about 4 months without issue and understand zfs uses 100%. Whats unusual to me is that it seems to transfer to extra ram use in the ram bar, then continue to rise ram until unstable.
