I have sniffer network traffic and I get these two messages. Can someone give me an explanation of what they mean.

Thanks

If you have the sniffer window open when this happens, my guess would be that it's the 'scroll buffer' (maybe) that is very large, and then the window size (literally) gets to large. Maybe your scroll buffer could be reduced.
I have been sniffing too, but never seen this issue (with net monitor, the complete edition).

I guess these are about the TCP protocol between two machines.

"Window size exceeded" means that machine A says to machine B: "You can send me up to n bytes of data". Machine B sends more than this. The window size is exceeded.

"Window frozen"means that machine A says "You can send me up to n bytes of data". Machine B then sends some data, but machine A achnowledges the data, but never opens its window any wider than that.
