Hi,

Can someone check this out, been getting these spikes on server for the past couple of days. Not sure what to make of it but here is a trace

These are normal - when a Cisco router runs the BGP scanning process, it will often cause icmp requests and such to display higher latency because these packets are treated as low priority. If you ping from end-to-end simultaneously while tracerouteing, you'll notice that while the traceroute displays higher RTT's, the ping never fluctuates. This is because flows through a router are processed with the highest priority, whereas packets that are directed to a router (or directly connected interface on a router) are treated as the lowest (this is how traceroute works).

Thanks for the reply, the reason I started doing the traces is because I have noticed in game (Call of Duty) that high pings also show the spikes. Are the game ping request treated the same ? I just started seeing this recently.

The server is running 1 32 player COD server and nothing else, it is a Dual Xeon box , I have adjusted my max rate in game and the high latency is still there no matter what I set it to.

Does the BGP scan only happen at certain times ? or is it constant ?

Thanks

Does your server do anything aside from host that CoD server? How does your CPU use look during your lag spikes?

I have a 64man mohaa spearhead server, and its spiking wildly, and i just got this customer on this box, dual xeon , bad impression, CPU is at %25 steady

What's the matter with the network? Everythings average on my end

308mb used outta 2gb.......dunno whats the problem

The only thing the server is doing right now is host CoD, I don't have any web sites etc. on it. I do have 1 20 person Teamspeak server on it.

CPU usage is ok it peaks at around 15% during map changes etc....it's a dual Xeon so I doubt it is anything being overloaded. I'll check the CPU tonight during the spikes to see what it is exactly.

one funny thing that I noticed is that I installed a 20 person CoD server on it today and used a different IP for it. It doesn't have this problem at all. I wouldn't think one IP is better than another on the same box would it ?

Thanks for the great customer service you guys give us

I've had about 10 or so of my CoD players complain of the same thing.

I've noticed the same problem.

I'll post the traceroutes from some of my users when I can get them to do it.
