Good Day:

I have a situation where my PC is generating over 30000 TCP DUP ACKs in a sec as per wireshark. This overwhelm the WAN circuit obvioulsy.

I have no clue what triggers this.

My first guess would be a bug in the TCP stack.(windows platform)

This situation is very intermittent and occured at 5 different locations so I donlt think it is an attack.

Any help is greatly appreciated.
