you had a loop on a portfast port, BPDU guard prevented that from  
causing it to melt your network down.
you should be thankful.

i've seen loops caused by all sorts of things.  some virtualization  
software does it.  some vendors' iLO ports can be bridged with a non- 
iLO port, and some teaming/"failsafe" NIC drivers can do it.

my suggestion is to find out the root cause and fix that.
