Hello List, I am running throughput test between to Athlon 64 X2 with Stable 6.x 386 mode. I have 100 vpns and 100 gre tunnels. The gres go thru the vpns. I am using nttcp to do the the thruput testing. When I use FAST_IPSEC I get better performance than standard ipsec but I also get a lot of the following messages: Apr 28 10:44:48 J301001 kernel: gre45: gre_output: recursively called too many t imes(2) Apr 28 10:44:54 J301001 kernel: gre58: gre_output: recursively called too many t imes(2) Apr 28 10:44:54 J301001 kernel: gre95: gre_output: recursively called too many t imes(2) Apr 28 10:44:58 J301001 kernel: gre80: gre_output: recursively called too many t imes(2) Apr 28 10:44:59 J301001 kernel: gre67: gre_output: recursively called too many t imes(2) Apr 28 10:45:04 J301001 kernel: gre73: gre_output: recursively called too many t imes(2) Apr 28 10:45:08 J301001 kernel: gre64: gre_output: recursively called too many t imes(2) Apr 28 10:45:19 J301001 kernel: gre20: gre_output: recursively called too many t imes(2) Apr 28 10:45:19 J301001 kernel: gre54: gre_output: recursively called too many t imes(2) Apr 28 10:45:24 J301001 kernel: gre72: gre_output: recursively called too many t imes(2) Apr 28 10:45:28 J301001 kernel: gre14: gre_output: recursively called too many t imes(2) Apr 28 10:45:28 J301001 kernel: gre50: gre_output: recursively called too many t imes(2) Apr 28 10:47:24 J301001 kernel: gre4: gre_output: recursively called too many ti mes(2) Any ideas why this might be happening with FAST_IPSEC? Should I go back to the standard kame ipsec? Thanks for your insight, Steve -- "They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety."
