I report this problem in name of someone else (bigfoot). I don't have such (slow) hardware myself and can't reproduce therefore.

"512x512 map, 3 players, 300MHz P2 server (Linux, 0.4.5)... The game autosaves every month, and that sometimes takes so long that a few players get disconnected with "desync" error.

Moved the server over to the Peg1 (PPC/G3 @ 600MHz), no problem anymore

...

The whole game freezes on all clients while waiting for the server to save"

Maybe someone else can reproduce.

regards,
tokai

Reported version: 0.4.5
Operating system: Linux

Actually i thought threaded saving is used on linux and this should avoid such freeze/delay.. but it seems it doesnt?

OpenTTD can be compiled without threaded saving since win95 or something didn't support it the way we did it. Maybe the binary got compiled singlethreaded by accident. I have no way to test that theory so somebody else will have to do that. Another reason could be that the CPU gets so overloaded that all processes get so delayed that this happens.

From r2391 threaded saving has been disabled for the server, but I don't see anything against enabling it again. Although it won't help too much on an old PC, your best bet is to disable autosave for the server.

TrueBrain closed the ticket.

Reason for closing: Fixed

Thread saving on a server is a bad bad idea for various of reasons. So keeping it off for now seems like a very good idea. Closing bug.
