I had the problem when using a well-known filesharing service due to
excessive tcp connects, although I have just a 128/768kbps DSL connection.
I've set my nmbclusters to 1024 and have never seen the problem again.
IIRC I still had the problem with nmbclusters=512. Well, e.g. "ping -f -s
1450 someone" results in "No buffer space available" after less than 2
seconds. I'm not sure whether that depends on nmbclusters aswell.
