Hello,
My server became unplayable since updating to the latest version. There were absolutely no issues in v20.3.
Setup:
Dell PowerEdge 420 with:
two quad core xeon E5-2407v2 processors
70GB DDR3 RAM
Gigabit connection with 2ms PING
OS: Ubuntu 20.04
Players:
2 external
1 internal on the local network (me)
Server config xml settings:
I set all the data exactly as in the old xml(which was completely stable). In the new xml the only thing that I had to set differently were the two lines regarding the region.
No mods are used.
Networking settings:
<!-- Networking -->
<property name="ServerPort" value="26900"/>
<property name="ServerVisibility" value="2"/>
<property name="ServerDisabledNetworkProtocols" value=""/>
<property name="ServerMaxWorldTransferSpeedKiBs" value="1024"/>
Behaviour:
Extreme lag and rubber banding happens so often that the server is mostly unplayable. During horde night the two external players were kicked by the EAC because of the lag. As soon as that happened, and I was the only one playing, the lag and rubber banding disappeared.
We got the same thing happening while in a test server on one of the external players local server.
Console:
I am using Telnet to monitor the server remotely in real-time (I keep the game on one monitor, and the server console on the other one). No errors appear on the server console, except for skipped ticks caused by player lag. During horde night while all the players experienced extreme lag,( so much that we did not even get to see zombies)but the server was behaving normally, spawning zombies and getting them killed by the turrets and various traps. Processor usage was normal. In the end the players were kicked by EAC for lagging. At one point we were 5-7 seconds behind what the server console was showing.
What is going on here? It is clear that it is not a performance issue on the server part, or else I would have seen high processor/network usage. I have a hunch that there is something fishy going on with the steam connection/game network.
Any suggestions?
