Zombies do not spawn on LinuxDedicatedServer and other problems.

We may have found the cause.
It seems that Screamer is spawning all at once up to the "MaxSpawnedZombies" limit at some point.

We have the same problems on our Windows Server. A restart fix it for a while. Sometimes the player could play four hours, another time it ist after one hour

I added a setting that prevents Screamer from spawning and the problem does not occur and it is still stable on b324.
I borrowed the following URL for the modifications I introduced.
https://www.nexusmods.com/7daystodie/mods/3149

We had try it, but after 2 hours the bug was there again 😞

This does not apply to already spawned screamers.
All entities (including players) can be removed with the "killall" command.

9 hours ago, trueagain said:

Dies gilt nicht für bereits gespawnte Schreier.
Alle Entitäten (einschließlich Spieler) können mit dem Befehl „killall“ entfernt werden.

I know. We had kill all and a restart. But sure it could othere reasons why problems there again. It was one time since yesterday. We will test it the hole weekend

I'm late to the party, but I'm not very good at English.
Sorry if there are any errors in the translation.

 

Hmmm
For your information, my server reboots every 6 hours and there is always someone logged in, over 30 people during peak hours, but I have not experienced any major problems.
Except for a few rare unexpected server outages, but those are rare.

 

I believe the zombies stop spawning because the "MaxSpawnedZombies" limit has been reached, what is the result of the "le" command?
Example: Total of 72 in the game (72Entitys = Player + Trader + Enemy + Animal + Vehicle + Drone + DropItem + EntityLootContainer)
When the zombies stopped spawning on my server, for example, the breakdown was as follows
Total of 535 in the game
Enemy = 500
Player = 12
Other = 23
MaxSpawnedZombies = 500

Sorry, my mistake.
It seems that even if I stop the screamer from spawning, the error still occurs and the zombies do not spawn and other problems continue to occur.
Hopefully this issue will be fixed soon.

We have test something and maybe it is the problem of this issue. 

Look at this post it is a player on our server. He have start a discussion.

 

I have take a look in th 7days Discord, the opinion there from "experts" it is no bug. I think it is and one person have it with 6 Players and Vanilla Server

 

 

This is happening in our server as well, the more users joining and leaving worst it is.

 

May I added some log outputs as well?

Those errors are shown in our server right before the zombies spawn becomes bugged, it may randomly crash after people leave, plus there is many unexpected server shutdowns /day, **and becomes very unstable once we hit 20~30 people in.

Can someone with these issues post both FULL client and server logs from the same session?

Sure, I won't mind as long as it is through a private channel, because of players privacy. I don't know about client logs, I can try to ask our community members

 

This issue is caused by quests. its kinda random if it happens or on a quest or not, maybe its related to the kind of poi. fetch quests causing it the most. As workaround you could simply edit the dialog.xml and remove the possibility to start quests at trader.

We have confirmed that the same problem occurs in A21.1 b6.

The screener issue also continues.
I have responded by continuing to disable the screamer.

I made the following changes on my server and the problem seems to have improved somewhat.
But verification is inadequate.

・blocks.xml
　<property name="HeatMapStrength" value="0"/>
・sounds.xml
　heat_map_strength="0"

 

A21.1b16 seems to be stable without the above problem.
However, after the update, there is a phenomenon where the FPS drops unexpectedly and then improves after a while.
This behavior seems to occur not only during quests and base activities, and was not seen before the update.
