Cisco to Juniper High CPU

I have a juniper switch as the main switch in my network. I have a trunk setup and a cisco 3750 connected to the Juinper. But on the 3750 Spanning tree is killing the CPU.

I have STP disabled on all VLANs on the cisco and on the juniper I have STP disabled on the trunk port.

CPU utilization for five seconds: 65%/8%; one minute: 64%; five minutes: 64%

PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process

226 53335491 103663000 514 49.20% 49.37% 49.31% 0 Spanning Tree

This is what my CPU looks like with only 3 clients connected. Any ideas of what I can try to solve this?
