Hi guys,
I have a very interesting problem on one of our servers. Over the last few days, the network speeds have gotten ridiculously slow. Downloads (wget) that normally saturate the port are now at about 10mbps. Downloads from servers that are still close in proximity to ours (i.e. LA, Phoenix, etc.) still saturate the port.
Sounded to me like a routing or network issue, but that isn't the case. There are no dropped packets, no packet loss, etc. Our DC checked the router and switch, and everything checks out fine. Other servers on the same switch are doing great.
To further confuse matters, they put the server into rescue mode, and speeds were normal. This indicates something on the server itself that might be causing this. I'm still going to ask the datacenter to replace the ethernet cable and try a different switch/port, but in the meantime...
What the hell could be causing this? ha ha! I've exhausted pretty much every option short of reinstalling the OS, which I really don't want to do since there are clients on this server. I've run with/without firewall, flushed the iptables, turned iptables off, turned nat tracking off, reset the network card, you name it.
Anybody have any suggestions?
