0.12.29 Headless sever desync into hang

[NoPantsMcDance]

My vanilla server had a player desync then the server hanged afterwords. If I forgot to upload anything lemme know, side note the desync report was in the "temp" folder instead of "archive" not sure if that's intentional or another bug.

The server was the one out of sync, it seems all players disconnected when it tried to download the map from them, leaving the server hanging without a player or a map and therefore could not finish the report.

Yes, the server should always consider itself as the primary source of the data when possible.

But the desycns shouldn't happen in the first place.

Got same here i think.
Server is a 0.12.29 x64 headless Linux Debian

if i can provide more info i will do, just tell me. May "peer-to-peer" could render that "Server is Primary source" ignored? Would disabling peer-to-peer Change something?

The question imo is if the players diconnected cause they closed the game or because the server is unable to keep the connections if it desyncs itself. Players should not leave until the first map upload is completed so that the desync-report can be created.

Oh, thanks for the report, this is actual logical issue in the server logic.

The server actually got desynced, and then he had no one to download from, we solved it for 0.12.30, by forcing the server to never be the one who desyncs even if there are more players with different crc.

Where's that "like" button when you Need it?
