Self-oscillation problem...

Self-oscillation problem...
i have built a few state-variable filters, and they all seem to suffer from what sounds like self-oscillation when you have the resonance and frequency both up high. it doesn't seem to be a problem with the frequency low.  
has anyone run into this, and how can you tame self-oscillation?  
with the addition of an envelope follower and external CV pedal in, this will make a cool wah/envelope filter hehe  
thanks :)
