That's that main problem that causes the server to crash and require powercycle to come back up. It would only stay up for a few seconds on high traffic. mbuf clusters have been increased to 65535 131070 was attempted but server did not like it and won't boot up. Server has 2 gigs of ram FreeBSD 4.6-RELEASE fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0x1400-0x143f mem 0xfeaa0000-0xfeabffff,0xfeae0000-0xfeae0fff irq 7 at device 3.0 on pc i0 fxp0: Ethernet address 00:03:47:a4:fb:23 inphy0: <i82555 10/100 media interface> on miibus0 inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto fxp1: <Intel Pro 10/100B/100+ Ethernet> port 0x1440-0x147f mem 0xfea60000-0xfea7ffff,0xfea80000-0xfea80fff irq 9 at device 4.0 on pc i0 fxp1: Ethernet address 00:03:47:a4:fb:24 inphy1: <i82555 10/100 media interface> on miibus1 inphy1: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto netstat -in Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll fxp0 1500 <Link#1> 00:03:47:a4:fb:23 7943967 2 11631732 1 0 fxp0 1500 66.28.252/xx 66.28.252.4 1175 - 11638120 - - fxp0 1500 66.28.252.xx/ 66.28.252.17 1346 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.18 90206 - 0 - - fxp0 1500 66.28.252.x/x 66.28.252.7 2696087 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.11 2 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.13 13 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.25 13 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.28 5152357 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.29 13 - 0 - - fxp0 1500 66.28.252.xx/ 66.28.252.30 56 - 0 - - fxp1* 1500 <Link#2> 00:03:47:a4:fb:24 0 0 0 0 0 lo0 16384 <Link#3> 148 0 148 0 0 lo0 16384 127 127.0.0.1 148 - 148 - - Load and Cpu is good but crashes on Mbuff error.
