Out of Memory Error Minecraft

What Causes Out of Memory Errors?

Usually, out of memory errors is due to your server running out of RAM. The cause is a bit more difficult to determine.

Note that every Minecraft package has a set amount of RAM. The use of plugins will use up this RAM in addition to each user on your server taking up a chunk of RAM themselves.

Common causes:

• Too many plugins for the available RAM
• Using multi-world plugins (each world uses a lot of memory even if no players are on it)
• Out of date or incompatible plugins
• Memory leaks caused by mobs, lava, water, redstone, pistons, or entities

Solutions

1. 1Reduce plugins — Remove unnecessary plugins to free up RAM
2. 2Limit worlds — Reduce the number of active worlds
3. 3Update plugins — Keep everything up to date to reduce incompatibility
4. 4Upgrade RAM — Consider upgrading to a higher RAM plan
5. 5Lower player slots — More plugins + fewer players = more stable
6. 6Remove entities — Clear excess mobs, items, and other entities using /lagg clear and /lagg killmobs
