# 💻Out of memory error

---
This error means that the server has fully used up all the RAM that has been allocated to it. Once the server runs out of memory, it can no longer store or process data, which usually results in crashes, lag, or the server completely shutting down.

### Why does this happen?

Servers use RAM to store all the active runtime data — this includes plugins, mods, world data, entities, chunks, and anything else the server needs to function. When the usage reaches the limit, the server cannot continue running correctly.

---
## How to Fix It

There are a few ways to resolve this issue depending on your setup and requirements.

### 1. Remove or Optimize Plugins / Mods

If you're running a large amount of plugins or mods, some may be heavy on memory usage. You can:

- Remove unnecessary plugins or mods.
- Replace memory-heavy plugins with lighter alternatives.
- Check for memory leaks (plugins that use more RAM the longer the server runs).
- Lower view distance in your config files.

### 2. Reduce Server Load

Things that increase RAM usage:

| Feature | Impact |
|--------|--------|
| High render/view distance | Very High |
| Large amounts of entities (mobs, animals, etc.) | High |
| Many loaded chunks | High |
| Heavy modpacks | Very High |

Reducing these can significantly lower RAM usage.

### 3. Purchase More RAM

If your server still runs out of memory after optimizing, the simplest solution is to upgrade your plan and allocate more RAM. This will allow the server to store and process more data without crashing.

# ⚠️Error: Unable to access jarfile server.jar

---

# 🧳Server Resource Packs (Minecraft)

---

To add a custom resource pack, you will need to upload your resource pack via one of the following options:
- A public dropbox link
- AtomicHost webserver

#### A public dropbox link:
1. Upload your resource pack .zip to dropbox and make sure it is public
2. in your `server.properties` file on your server, find where it says `resource-pack`
3. after the `=` paste in the link in
4. ***IMPORTANT:*** Make sure at the end of the link it says `?dl=1` not `dl=0`

#### AtomicHost Webserver
1. Purchase an [web server](https://atomichost.xyz/store/website) (make sure wordpress is turned off).
2. On your server, in the `webroot` folder, upload the .zip file
3. On the server console, copy the ip, and paste it into your browser
4. on the end of the link, put in the name of the file, e.g. if your .zip file is called `pack.zip` you would put `https://atomichost.live:0000/pack.zip`
5. in your `server.properties` file on your server, find where it says `resource-pack`
6. after the `=` paste in the link in

***You will have to restart your server to see your changes be affected***

# ⚠️Current Java is 17 but we require at least 21

---
This error may not be exactly the same, but the fix to this is to change your java version to the java version which the error requires you to use. For an example, in this error:

`Exception in thread "main" java.lang.IllegalStateException: Current Java is 17 but we require at least 21`

It states that we are using `Java 17` but the version of Minecraft we have installed requires `Java 21`. 

To change the java version, head over `Settings` and change the `Java Version` Varible to the correct java version.
