    Stepping back outside of potential nuances with the applications you mention, are you seeing any FIN ACKs? Any specific hosts the TCP 1026 is originating from? Any specific patterns to the traffic? Is it causing problems? One of the best things you can do is to connect a network analyzer such as OmniPeek (or Ethereal if you're willing and eager to take that on) to the network segment and see where the traffic is originating, etc. The reason I like commercial products like OmniPeek is because you can it in "monitor" mode to get a much simpler representation of what's going on. WELL worth the money.
