EAGAIN error

anarchogeek · Post by **anarchogeek** » Sat Apr 02, 2005 4:00 am

Hi. I'm running a server on Windows XP (*crowd gasps at Happy Tanker's stupidity*). Anyway, it can only handle one client. It does this:

Player Happy Tanker Admin [1] removed at 2005-04-01 22:56:00: Write error EAGAIN

if more than one client tries to join. What's causing this? Any more information you need?

Mine does that too. BIYA's does that too.

The similarity: We're all trying to run a server in Windows. There's been a Windows bug in the server ever since forever, and nobody can figure out what's causing it. I just gave up and installed Linux as a second OS.

I got write error EAGAIN on my server before but i managed to somehow fix it, it's a problem with flags.

Set a -f good in the config and don't set an +f good {number}

Well i g2g to school now, brb in 6 hours tell me if it works.

hmm.. If you stick too many flags on a map, you cannot spawn.. I wonder if this problem is related to that...

+f good{40} is the breaking point on my machine.
you can use +f good{N}, just keep N reasonable.

Excellent. Thanks for the help. Just out of curiosity, why does this vary between operating systems? On Linux, I was able to insert over 200 flags of a particular type with ease, but on Windows I have this 40 limit. As examples...

BZLand running on Linux server. 50 Wings on map.
bzflag.norang.ca:5155

BZLand running on Windows server. 30 Wings on map.

Anyway, it works great now. Thanks for all the help.

ARGG!!! I'm getting it again, but it just happens after more people have joined. Seems about 5 people.

I'm telling you, it's Windows. There has been a problem with BZFS and it's compatibility with Windows for a long time. The problem hasn't been tracked down yet, so for now BZFS will never be reliable on Windows.

Well, we won't get anywhere without people whining about the issues

.

Here's a partial debug from the server.

Even though it looks like it here, the problem is NOT always specific to remote clients. It often happens to me.

I'll whine too, I get the exact same output on Windows.

anarchogeek · Post by **anarchogeek** » Wed Apr 06, 2005 1:37 am

Notice, also, that EAGAIN occurs only when someone has been accepted multiple times on the same connection (it appears that a list bot is logged on in the given player number every time someone attempts to logon to that same number). This is marked in blue in my table above.

I, therefore, believe that this WOULD NOT occur, were the map being served locally without bots in my face, and that this is the sole creation of the bots. This particular form of messup appears to be linked directly to operating system, nonexistant in on *nix machines and Macs.

Same, after five people no one can join. Seems quite suspicious that in XP Home there's a five-computer network limit.

as stated in another thread, windows XP has a connection limit. If you are going to use XP as a server, you will want to modfiy your settings ( your XP settings, it involves messing with windows files ). to allow for winsock to have more connections.

Or change to a version of windows that dosn't have the same limits ( 2000, or one of the 'server' Versions ).

Yes it was mentioned, but you didn't link a patch for it. I've been googling it all day, no luck. Do you have a link?

The SP2 half-open packet issue to which you linked a hack for can produce the same error, but is clearly not the problem considering I'm not on SP2.
