Is NOk a bad thing?.

I have 1 cachex mode 3 line to this oscam from another cachex oscam with many cachex peers sharing cache, In additon I have 1 n line from csp; and 2 n lines form my card reader oscam

Any suggestions how to:-

1. reduce /eliminate NOK

2. Increase cache form cachex oscam?

I think 1 and 2 are related?
