i get a server disconnect/reconnect every 5-6 minutes or so through port 5009 (streaming quote); the output looks something like this (removed token):

1- what is the reason for this? is this normal? how do i resolve this?
2- a disconnect loses my watch list and i have to recreate it; that means that i may lose tick data (yeah, i know, i can retrieve the historical ticks on the other port for the missing time, but that's just making it complicated); that's not a good thing; what's the work-around?

thanks,
andrzej

andrzej,

Is this problem still existing, or has it stopped?

Also, what quality of Internet connection are you using?

Steve,

this problem still exists, and existed yesterday evening too. i have sbc dsl service here in dallas, with a dynamic ip; but the ip is assigned only at connect time, so that should not be an issue.

I talked to one of the Software Engineers. They would like to know what kind of hardware you are using.

andrzejs,

OK, I think we have something here. I'm told we have seen a frequent problem with Dell's using an integrated network card. If this is the card that came with the Dell, then it's probably an integrated network card. Try another network card type and see if that doesn't solve the problem.

I have had a similar problem although nowhere near as frequent....perhaps twice per day.

andrzejs: Has the ethernet card in your laptop performed well otherwise?

Steve: Do you have any further info on the cause of these dropouts? Does the Dell have a
known problem or is it just circumstantial evidence?

I am using an HP with an Intel PRO/1000 MT. I could switch to the onboard 82540EM port.

dhakme,

We aren't sure why this fixes the problem most of the time, but not always. We discovered this internally by accident.

As for your small problem with the HP: Give it a try and let us know what happens.
