I have been playing on a server with my friends for a while using curseforge. All of a sudden the other night i cannot go into a specific room we built. I comes up with the following error:

 

[Server thread/WARN] [Canary Class Analysis/]: Canary Class Analysis Error: Class com.talhanation.smallships.entities.AbstractCannonShip cannot be analysed, because getting declared methods crashes with NoClassDefFoundError: com/mojang/blaze3d/vertex/PoseStack. This is usually caused by modded entities declaring methods that have a return type or parameter type that is annotated with @OnlyIn(value=Dist.CLIENT). Loading the type is not possible, because it only exists in the CLIENT environment. The recommended fix is to annotate the method with this argument or return type with the same annotation. Canary handles this error by assuming the class cannot be included in some optimizations.

 

I have reinstalled the modpack profile many times to no avail. Any help would be greatly appreciated!

Post your logs/debug.log from the server so we can see the actual problem.

From the information you show, the canary mod is trying to load a client class on the server, specifically by loading a class from the smallships mod that references a client class.

But the warning suggests this is not the real problem.

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

      How many peole in theory could my server support on minecraft.

      By mojack66 · Posted

      Thank you for the suggestion if figure that it should be able to support around 40 based on my previous experiences hosting but no one really seems to have a concrete way of figuring it out. You have been alot more helpful than most people and i will probably set up Linux tomorrow.

      By Ugdhar · Posted

      Graphics are irrelevant for a server. According to google, it should support 20-40. I literally asked it "how many players on a lightly modded minecraft server will a ryzen 5 2600 with 32GB ram support?" Maybe someone with some real world experience has further input. I can say without a doubt that if you run Linux as opposed to windows for the server operating system, you will get better performance and have more resources available to your server.
