There's a seperate thread per machine its connecting to, and each thread opens a socket, transmits 8k, and closes. The problem lies with an error of 'No buffer space availible' within the first couple of seconds. I've tried the SO_SNDBUF& SO_RVCBUF, but that doesn't make sense in my head anyways. Anyone seen problems like this under similar conditions & maybe any remedys? -mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
