Headless server, Ubuntu 20

Someone logged in and the game stayed paused?

Race condition?
the RCON command is me remotely running a commmand to see if anyone is online when user reported server frozen ( took a while to respond )
I tried to connect, and server did not respond. Other Factorio servers on same machine were fine.
It shouldn't be a file/io problem. there is 16GB of write buffer available, writing to a NVME SSD.
Also seems odd that it is peer 11, he was the only player.

Can you provide a full server log/configuration?
I wonder... are you using the non-blocking save?

Posted: **Fri Mar 05, 2021 4:08 am**

Yes, non-blocking save is enabled.

Has this happened since? Do you have a way to reproduce it?

Posted: **Sun Mar 14, 2021 1:04 am**

For the moment, I disabled async save.
It happened very rarely, but it did happen a few times.

I will put it in my notes to see if there is anything specific correlated with it.

No idea what the cause is, but the freeze still happens (with async save off).
Only happens when a player is connecting.

log/saves/settings attached, Factorio 1.1.27.

00-06-00-32 AskMcEscher: save bug i think

When I connected, I got stuck at 'saving map' for some time, the progress bar was at 100% though.
Totally possible I just have a bug/performance issue somewhere I guess?

Async save is off in this case, so not sure it is related.
The log from the async save ( first post ) does still look odd to me.
Its odd that in both cases, the issue is always when a player is connecting... never seems to be on autosave?

Can you reproduce it without custom scenario?

Posted: **Tue Mar 16, 2021 11:10 am**

I'll investigate as time permits.
I'll give the scenario a going-over, do some performance testing, and possibly set up one of our servers with no scenario.

Thanks for the responses!
