Which version are you using? If you're using a recent CVS HEAD version,
make sure you check it out again since there was a little bug with a
recent change to initialization of tcp pcbs which has set some
connections in the closed state so that they wouldn't accept data. From
what you're saying, that _could_ be the reason...
