Unlike misfit, I'm more from the "what don't kill you will make you stronger" school...
Whch won't make anyone feel better!
Whenever I've made cabbagey things, they smell a bit ...intense...
there's a world of difference between the sulpherous whiff of lactic-fermented brassica and plain rotten stuff.
If you've been willing and able to eat it *despite* it smelling a bit high, I reckon it's ok.
Early cabbage tends to be a lot milder: is it your own?
As soon as I consider the kraut ready to eat, I jar it up and 'fridge it: I'm not wild about it when it gets really strong.
Sandor Katz gives really clear instructions on dealing with mould and as far as I'm concerned, it's all a matter of taste

btw: I'm just an internet construct, so please use my advice advisedly!
