Thanks a lot for this. Very useful for me

Sorry. I got no way to reproduce it.

I wasn't playing when it occurred. People just told me the server had crashed, so I collected the logs and posted it here.

It's interesting no more crashes happened so far. I think this is a rare crash.

The server just crashed. The log is attached.

I really don't know why people fighting in the other side of the map (a huge one) makes me lag.

Can't you improve the game so it updates just the area the player are near?

I just can't play on servers with big maps because of biters.

It is being uploaded on this same link: https://1drv.ms/f/s!Aj-x6YxxaqbohfkuGMdBt1o_B2tY3w

It takes a while, its a 276 MB Desync Report.

Also the map was generated on version 0.14.12. And we were playing on 0.14.13.

EDIT: File upload success!

He was catching up... I just saw that! Also, Desync! 956.473 Error ClientMultiplayerManager.cpp:90: MultiplayerManager failed: "You have been disconnected as you have been AFK." 632.951 Info TransferTarget.cpp:281: TIMEOUT at 0.554563 seconds 669.902 Info TransferTarget.cpp:281: TIMEOUT at...

My friend just got kicked for being AFK while he was catching up, on a huge map!

14.13 is not released yet, what version of the game are really using?

Sorry, renamed to 0.14.12.

All the people on the server waited about one minute for the map save. Also it happened many times with many desyncs.

Game still paused and saving while user already quit!

The user has desynced and quit but the game was still paused for a long time (about a minute).

It says: Server is saving the map for <unknown-user>.

Nobody can join my server anymore!

It gets desynced everytime!

Server specs: Ubuntu 16.04 64-bit, 4 GB RAM (Factorio + OS uses 2.36 GB), Xeon quad core, 40 GB SSD

How do I add this on my server-settings.json?

Added ignore_player_limit_for_returning_players option to the server-settings and equivalent when hosting from the game.

Added only_admins_can_pause_the_game into the server-settings

Thanks for your help! I have to buy a better laptop!

Can you check the CPU temperature before and during one of the lag spikes? Using something like Speccy: https://www.piriform.com/speccy Also, I meant in Windows. When you click the battery icon on the bottom right of your screen it gives options for what power mode you want to use: http://imgur.com...

Do you have it plugged in and is it on "power savings" mode or "performance" mode?

Its plugged in and its on High Performance mode.

I have a computer with these specs:

When I start attacking the biters, a HUGE lag starts to happen. The FPS drops from 60 to ~4 to ~5.

I got no anti virus, no bloatware and only windows 10 + steam + factorio running.
