was it unbrowsable on HTTP too, or just HTTPS ? > At this point, could it be a defective nic? Wrong kernel? I'm running > Fedora 12. Very unlikely. Hmm would this haproxy run on a dedicated machine ? If so, can you check its connectivity ? At least run "ethtool eth0" and check that your link is correctly detected as full duplex. If you could try a file transfer in each direction to confirm that you can saturate the link, it'll be nice. If the machine is dedicated, it's possible that you have iptables loaded too and that it quickly fills its conntrack table. You'd see that in "dmesg". Willy
