I've got 32GB, but it's a 3.2.0 kernel (Ubuntu 12.04 64-bit). I tried insmod ixgbe.ko RSS=1,1 FdirPballoc=3,3 mtu=1522 num_rx_slots=2048 num_tx_slots=0
but it didn't seem to make any difference. pf_ring is loaded with "transparent_mode=2 min_num_slots=4096" Best Wishes, Chris On 08/10/12 12:35, Alfredo Cardigliano wrote: > Christ > How much memory do you have on this system? > On my system (kernel 2.6.36, 4Gb of RAM, ixgbe) it is working fine. > Please try decreasing the num_rx_slots (actually memory allocation happens at > pfdnacluster_master boot, but it's worth giving it a try because it's > possible you are running out of memory). > > Regards > Alfredo > > On Oct 8, 2012, at 1:17 PM, Chris Wakelin <[email protected]> wrote: > >> Any ideas on this?
