Terk, I don't know what happened but ever since you said you fixed the "Rejected untracked stratum share from pool 0", my hash rate reported by your pool had gone lower than normal
I have a total of 10.8 MH/s of mining power, normally, the pool register an average of 10.2-10.5 MH/s which is good.
Now I only get 8.0 MH/s reported by your pool with a 0.3 MH/s rejected (3.5%), while all of my miners still do full speed which is slightly over 10.8 MH/s. No hardware rejection either.
You can check out the chart here.
