Maximum Spanning Tree instances in 6500

I have a 6500 switch with CatOS (6.x) and it supports max of 128 vlans. I have around 200 vlans in my network, so a lot of vlans do not have spanning tree instances running for them- (it gives me a message to that effect, when I create new vlans). Is there any way for me to get spanning tree running for all vlans? I use PVST+

hmm..CAT6500 does not have this limitation. Can you paste the error message?

You are probably confusing this with XL/3550 switches

Yes! U are right, the message was seen on the 3548 switch not the 6500. Thanks for the help.
