[1.1.80] Headless Server - Seemingly unavoidable crash at same point

[xeode]

Hi there,

Hoping someone can help, I went to connect to my long running Vanilla server the other day and found it not responding and after logging into the console of the server I see that the game has hung without any error. If I reload the last save within a consistent amount of time the factorio process stops responding and connected clients are also frozen (can't even load the menu). Factorio 1.1.80

If I load an earlier autosave all is well until the same time after the same numbered auto save. I have tried connecting just after the earliest autosave available (before going into the backups of earlier games and losing a few days of progress anyway) and connecting to turn off all factories and trying to stop any activities which might be causing a repeatable crash too. But seemingly whatever i do, a few minutes after autosave4 is saved and the game resumes, the same hard crash happens. I have found lots of cases of it crashing during save but it seems to be well clear of completing autosave4 by the time the crash happens.

Server itself seems to be fairly quiet when it happens and no shortage of disk space or other thing I could think to check and if I save the game to my PC and load it locally it seems to crash after the exact same amount of time. Have never had this happen before either local or mp and can't find anything about it through search, just those who are having issues during saving.

Save file if anyone needs it: drive dhowt google dhowt com/file/d/1peDjRlsquxww1-EALETNT7sm8YeHEBsA/view?usp=sharing

Are there any things I can do in game to try and alter the collision course before the deadly juncture rolls around or any extended logging that can be turned on to understand what it tries and fails to chew on, or indeed any thoughts at all as I'm at an impasse and have several years on this server now I'm keen to keep hold of.

Thanks for any thoughts that come to mind anyway.

Kind regards,
xeode

How long do I need to wait before the freeze happens?

Does it only happen if hosted as a headless server or does it happen if loaded as a single player game?

Hi there,

So this is the earliest save from the rotation so i could have as much time as possible to go run around and turn things off before the crash came but not sure how many minutes that is. It does seem to load and crash at the same point on the server and on the single player, will have another try and have a timer going. Thanks for having a look.

Kind regards,

Hi there,

Looks like it's about 37 minutes from that save, here's one that's a bit sooner if you don't need the time:

EDIT: dies just after 4 minutes after the above '_autosave3.zip', thanks for any insights.

The save file is 600 megabytes. Loading saves that large typically takes > 32 GB of RAM. Your computer shows having 16 GB which means it will likely be hitting the page file long before loading finishes.

If it ran out of RAM and started paging to the disk that will significantly slow things down. Did you run some "chart huge area" command? Why was the first save you provided 30 megabytes and this one 30 minutes of playtime later 600?

I think you provided the wrong save file the first time. The 2nd save file you provided is very close to the max play time possible on a given save (2.269~ years).

It looks like you disabled auto-pause and left the save running on the server while you weren't playing which let it accumulate time. There are some work-arounds people have done to continue playing but there is no official way to play past 2.279 years in a single save file.

Hi there,

Aaaaahhhhh! Never heard of a maximum world age or imagined there would need to be a register for every tick since 0 or whatever that equates to. Yes have been running the save for a long time, the vast majority of time running on my computer in Steam though. My home computer does indeed struggle to run it (45UPS with everything running) but on a 32GB server is only reserving 20 or so GB.

Ah yes very sorry have seemingly uploaded a completely different save at first beg your pardon! That looks like a space exploration one too doh.

Will have a look into the workarounds then as was hoping to run this just to see how far it could go etc and glad to find it wasn't some terminal corruption or something.

Thanks for your help!
