Long Fermentation

[mikfaria]

I made a batch of Raspberry Blonde last Wednesday. 7 days later, it is still going strong. I used White Labs California Ale. I've had to clean the airlock 10 times in the last three days, and there is still a thick krausen. Is this normal? Usually my fermentations are done and ready for racking at 5 days.

how big is your primary? could you have run out of headspace, and thus lost a significant portion of your active yeast? since you're still clogging your air lock.. just a thought...
