Hi; I have 2 links with 2 different ISPs on this firewall. On one link, everything is normal [~]>ping www.google.com PING www.google.com (64.233.185.104): 56 data bytes 64 bytes from 64.233.185.104: icmp_seq=0 ttl=44 time=175.683 ms 64 bytes from 64.233.185.104: icmp_seq=1 ttl=44 time=174.499 ms 64 bytes from 64.233.185.104: icmp_seq=2 ttl=44 time=171.770 ms 64 bytes from 64.233.185.104: icmp_seq=3 ttl=44 time=170.737 ms 64 bytes from 64.233.185.104: icmp_seq=4 ttl=44 time=170.705 ms 64 bytes from 64.233.185.104: icmp_seq=5 ttl=44 time=171.699 ms 64 bytes from 64.233.185.104: icmp_seq=6 ttl=44 time=178.248 ms 64 bytes from 64.233.185.104: icmp_seq=7 ttl=44 time=170.924 ms 64 bytes from 64.233.185.104: icmp_seq=8 ttl=44 time=174.189 ms 64 bytes from 64.233.185.104: icmp_seq=9 ttl=44 time=169.742 ms 64 bytes from 64.233.185.104: icmp_seq=10 ttl=44 time=171.725 ms on the other, I get this: [~]>setfib 1 ping www.google.com PING www.google.com (64.233.185.104): 56 data bytes ping: sendto: No buffer space available 64 bytes from 64.233.185.104: icmp_seq=0 ttl=39 time=2837.234 ms 64 bytes from 64.233.185.104: icmp_seq=2 ttl=39 time=1999.021 ms ping: sendto: No buffer space available 64 bytes from 64.233.185.104: icmp_seq=3 ttl=39 time=2256.407 ms 64 bytes from 64.233.185.104: icmp_seq=4 ttl=39 time=3002.886 ms 64 bytes from 64.233.185.104: icmp_seq=6 ttl=39 time=1570.676 ms 64 bytes from 64.233.185.104: icmp_seq=7 ttl=39 time=1765.401 ms 64 bytes from 64.233.185.104: icmp_seq=8 ttl=39 time=2148.457 ms ping: sendto: No buffer space available 64 bytes from 64.233.185.104: icmp_seq=9 ttl=39 time=2207.230 ms 64 bytes from 64.233.185.104: icmp_seq=10 ttl=39 time=1752.444 ms 64 bytes from 64.233.185.104: icmp_seq=12 ttl=39 time=1619.150 ms re0 - PROD-LAN re1 - LAB-LAN sk0 - ISP1 (fib 0) sk1 - ISP2 (fib 1) FreeBSD FreeBSD 8.3-STABLE #0 r204106 Wed Sep 17 10:28:45 BRT 2014 last pid: 6963; load averages: 0.00, 0.00,0.00 19:47:29 61 processes: 1 running, 60 sleeping CPU: 0.0% user, 0.0% nice, 0.2% system, 0.1% interrupt, 99.7% idle Mem: 210M Active, 3933M Inact, 1559M Wired, 516K Cache, 771M Buf, 1671M Free Swap: 16G Total, 16G Free This was at 7:oo PM but even during peak work ours it doesn't go lower than 88% idle when it peaks usage. I have one squid for each link with exactly the same configs and pf doing the round-robin between the two. This server has never done this before!. I've been googling around and tried a few suggestions but none really solved it. I have already set kern.ipc.nmbclusters from 32768 to 131072. It seemed to delay the "no buffer" message but it's back. My stats seem to me to be well bellow the limits.

The only thing I didnt do yet was to switch boards. Should I be looking into that? Any advice? Thanks, -- Mario Lobo http://www.mallavoodoo.com.br FreeBSD since 2.2.8 [not Pro-Audio....
