One thing that popped into my mind when I read your post is that the
documentation has a long list of DOs and DON'Ts for configuring SPAN:
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12119ea1/3550s
cg/swspan.htm#1036816
It wouldn't hurt to go through the list, line by line and check to make
sure your configuration is fully compliant.
HTH,
Jonathan
