Bruce: I'd recommend that you switch all your cores to server=llrnet.ironbits.net and port=400. IronBits' servers are rock-solid steady, you shouldn't have one iota of downtime with those whatsoever.

It's not the server, it is a limitation of llrnet, put enough machines connecting to any one llrnet server and it will fail.

server = "llrnet.ironbits.net"
port = 400
Let er rip!
And I agree with Beyond, especially if they are using a personal proxy server to connect to the main server.
Beyond should be able to tell you about how many clients a server can handle before it pukes.
From my experience, if a personal proxy is used, it causes communication errors.
If only clients come in, I've not seen enough clients coming into the linux server to see when/if it will lock.

Yes, but we've noticed that a server running on Linux is much, much more stable than one running on Windows, and it can handle a heavy load much better. It also doesn't barf when exposed to a personal proxy, like the Windows one does.

Personal proxies don't take down the server because it runs out of sockets like it does when using the windows version, but, the personal proxys will eventually cause it to fail.
That's one of the main reasons I moved all the servers to CentOS Linux because it can stay up longer.

I'm confused...are you saying that personal proxies are bad for the Linux servers, too (though not as bad as for Windows ones)?

Sorry, but yes the Linux server will fail too. As part of my testing when we were setting up IB's server it failed several times, I then tried it on one of my work servers (redhat enterprise) with 8 processors 32MB RAM on giganet connection and it failed too. Once you get in the 50 to 55 clients connecting range it starts to cause problems.

Oh, I see.

Well, then, I guess we'll just have to do future Drive #1 rallies on port 300/port 400 split (and possibly some on Lennart's port 6 server). That's the only downside to having such a large boom in project participation!

I can host too a llrnet server, just need to apply the patch to open more connections on win XP.

Thanks for the offer, Carlos--right now, with three different servers on the 400<k<1001 range, we should be all set, but if we need any more servers we'll be sure to let you know.

When I get the time I'll prepare everything on my side to guarantee another server for the project. Just need to open TCP/UDP ports, apply that patch and make a small test. The server will be host on a 2GB quad-core machine. Anyway, I am a backup....
