Hi, Are there any known issues when using nbd over machines having gigabit ethernet cards? I have 2 machines with Intel 850 motherboards and Intel gigabit ethernet card, and linux kernel version 2.4.18-5smp. NBD seems to choke at data transmission rates close to 15MBps. The dmesg throws up the error in the dmesg log - req should never be null. Any help in this issue will be appreciated. Thanks in advance, Hari
