>> Server should be as fast in Windows as in Linux, but Windows gtk is
definitely slower.

I think that the problem is Windows gtk.

...or network (connection between server and client) buffers overflowing with
such a massive amount of data. That could happen if for some reason server is
sending data faster than client accepts. Server should be as fast in Windows
as in Linux, but Windows gtk is definitely slower.

Follow-up Comment #9, bug #17962 (project freeciv):

What kind of hardware you have? I just wonder if this could be simply problem
of map generation taking so long that connection between client and server
timeouts? Or server running out of memory for such a massive map?

could you test, if the server of the windows build prints some usefull output
before it exits (i.e. start the sever seperate)

Follow-up Comment #6, bug #17962 (project freeciv):

I did load the four scenarios without problem with S2_3 on an Ubuntu 10.10
32bit.

It must be a problem with windows binaries...

Follow-up Comment #4:

Another data point:

User GM1350 on the forum, who's put together a number of large map scenarios
, reports in email that they
cannot load some of them in the Windows version of 2.3.0-beta3, but they can
load others (see thread). I think the examples mentioned were:
* europe-332x264-v1.8.sav.gz 
* middleeast-400x300-v1.1.sav.gz

* earth-500x250-v1.0.sav.gz 
* italy-420x300-v1.0.sav.gz 
GM1350 writes: "If I use my maps (ex. Earth) and I select this map in
''Scenario Game'' (on Windows Vista).. I see this:

Starting server...
Welcome to the Freeciv version 2.3.0-beta3 (beta version) Server at port
5556.
You are logged in as 'Administrator' connected to Administrator.
Established control over the server. You have command access level 'hack'.
Administrator: 'set topology "WRAPX|ISO"'
Option: topology has been set to "Wrap East-West" and "Isometric"
(WRAPX|ISO).
Lost connection to server (read error)!

"But freeciv-server.rpt is white!"

Which seems to indicate that the server has crashed.

I haven't tried to work out in detail what's different between the reported
working and non-working ones. The non-working ones tend to have a larger
number of tiles, but there isn't a simple threshold in number of tiles that
says whether or not it'll work.

However, I have no trouble loading any of these scenarios on Ubuntu Linux
10.04.2 on x86_64 (64-bit), either in a client-spawned server or in a
standalone server (and I don't see any errors or warnings in the latter),
either with 2.3.0-beta3 or the head of S2_3.

Similarly, I have no trouble generating maps where size=90.

So it looks like we're dealing with a Windows-specific server crash, which is
a shame as I don't really know how to get good post-mortem diagnostics for
Windows.

I guess it's also possible that it's an issue when Freeciv is compiled for
32-bit architectures -- some quantity that needs to be 64-bit is not? Can
someone confirm whether the above scenarios work when compiled for some 32-bit
Unix platform?

Possibly running valgrind on Linux will show something up; I haven't tried it
yet.

Follow-up Comment #3, bug #17962 (project freeciv):

(I assume there are two different anonymous people having a conversation
here?)

To the original reporter: it might help if we can see your settings. Can you
type "/show all" in the pregame window and paste the resulting output here?

Also, can you try with a standalone server (rather than a client-spawned
one)? If you can reproduce this that way, you should be able to see any error
messages the server produces before it dies, which would be useful to know.

I have tried it many times with two different PCs, first running on Windows 7
and the second one on Windows XP SP3 and many different settings but with no
success

Follow-up Comment #1, bug #17962 (project freeciv):

I am able to generate maps up to size 128 with 2.3.0-beta

although it does it errors about being unable to create starting positions (I
used 126 players with 120k tiles), it doesn't lose connection with the server,
and the game starts normally with a huge map.

I'm using Ubuntu 10.10, not windows, maybe this is a windows issue
