BUG - Game incredibly slow/freeze at start because because of 1 player.

[Atrik]

A27 has a new bug that occurs, reasonably often where a player will make the game freeze or incredibly slow.
What we currently observe : This isn't some kind of lag, the player won't experience network, nor cpu lag when this occurs.

Since this isn't creating any logs, how can we help document this bug?

I also had this happen a few times where everything but the ambient sounds froze. But no logs...

If you experience screen freeze/0ad freeze it might be a different issue, I believe in the case I describe the player can still control the camera for example. The above also seems to happen 1/10th of games.

You can decrease the BAD NETWORK constant in net server.cpp or some file in the source code to print out the lagger at earlier times. Also don't allow this value to be increased by lag.

Could or could not help idk, it's not network related.

It looks like similar behavior of game stuttering due to PC performance
Are you referring to cases where no unit moves and no orders are executed, but the GUI and camera remain responsive? 
I’ve also noticed that in cases like this, hosts start kicking players until units begin to move again. But after the suspected bugged player rejoins, the game continues with exaggerated stuttering.

Yes that's exactly the symptoms. IIRC I've already been that player who slows the game and I didn't experience any lag, not network, nor pc. Every time this happens, the buggy player doesn't believe others when they say he is lagging ("My cpu is at 15%" "I've just run a speedtest"). But kicking him out clearly solves the issue. It really happened to a very wide variety of players, and with enough occurrences to believe it's a bug of the game rather then any external factor.

How do you find out which one is slowing the game ?

The host kick players 1by1. Then once the buggy player leave, simulation run again, once he rejoined, the game is stopped or incredibly slow (slower then x0.1).
This never happens mid game, it's always at game start, but the player can rejoin and he'll still stop the simulation.

Is it never observers causing this?

Does who is hosting matter?

What OS are the players on that trigger the issue?

Is there a video that could be shared to have a better impression of what the issue looks like for involved players?

What versions does this happen with, 0.27.0 and 0.27.1?

I've experienced this as host. Max Lag for observer set to -1 on my case. Didn't test kicking observers.

I've experienced this with at least 3 different hosts that often hosts games, including me as host.

Idk, will ask next time

I'm not sure but I think it happens with both versions. Currently using 0.27.1 but i'm not sure if everyone is using it
