Are you sure??  If you are referring to the "fNumBytesToStream" variable in the "ByteStreamMemoryBufferSource" class, then note that this variable is checked only if "fLimitNumBytesToStream" is set, and in that case "fNumBytesToStream" will always be set (see "ByteStreamMemoryBufferSource.cpp", line 55).

I'm not saying that there can't be a bug in this code, but if there is, I don't think it's what you're describing.

I don't see how that can happen, because the socket is non-blocking.  If the client disconnects, then the call to "send()" should return (with less than the expected number of bytes written).  At that point, the server won't try "send()"ing to the socket again until it becomes writable again (which won't ever happen if the client has disconnected).
