If you have hubs connected to the 2950's then you may have a loop somewhere in your network ,also i would never turn off spanning tree on any network , it doesn't take up many resources for the protection it gives you . You also may see something like this if you have access points connected across mutliple switches and people roam between them .
Phil - I have seen this in the past when someone creates a loop by connecting up a hub or a server with two NICS, or bridging multiple VLANs..I would check and see if somebody added a device to the network. Once you find that you may have to find the root port of the switch where the device was added and shut/no shut to break the loop.
