I have rxd and txd set to 1024. How high can I safely go? # add more descriptors to em devices. hw.em.rxd=1024 hw.em.txd=1024 ### other settings... I have tried rx_int_delay=0 and 32 ... doesn't seem to make the watchdogs go away. dev.em.4.rx_int_delay: 32 dev.em.4.tx_int_delay: 66 dev.em.4.rx_abs_int_delay: 66 dev.em.4.tx_abs_int_delay: 66 dev.em.4.rx_processing_limit: 300 I am using a PCI-Express (x8) PCI-e slot according to the motherboard specs: http://supermicro.com/products/motherboard/Xeon3000/3210/X7SBi.cfm Rudy Jack Vogel wrote: > Increase the size of your TX ring, meaning the number of TX descriptors. > > You said this is a quad port card, what size PCI E slot are you in?
