the limit is 1024 for a terminal, and 4096 for a cpu server. if you get a failure at a lower number, then it's not because of concurrent connections, but something else. i know the original nix tcp code had trouble with zero-window probes. i'm not sure if the same was ever true of the distribution. - erik
