Ok, this looks a bit more tricky. Please check /proc/xenomai/irq during runtime of your test if there is the interrupt counter related to your RT-NIC driver (which driver, BTW?) is increasing. If it is not, your buffers get sent but will not return to the socket pool, thus you run into that error. Jan
