Hey fellows my server has crashed multiple times today with this crash log (It’s 17 MB so that’s why it’s a download): Spoiler: Start of the crash log Code (Text): ---- Minecraft Crash Report ---- // Quite honestly, I wouldn't worry myself about that.

This would also explain why the crash log is this big, because it’s parsing all the threads. In the crash-log itself I can’t really determine which plugin is causing this but my guess would be featherboard so I’m tagging @Maximvdw . I checked my memory usage and it’s totally fine 10 gb is “available” for system recourses and system thread limit is set to something like 223500 which should be enough and the user thread limit equals the system thread limit (I changed this after the crashes to check if it would help which it did not). Edit: This crash started to occur after I downloaded an updated version of this plugin: https://www.mc-market.org/resources/6611/updates I also did a lot more things so I’m not entirely sure if this plugin is really what started the crashes. The crashes mostly occur after like 3 / 4 hours. I just removed the spoofmachine plugin and I’ll keep you guys updated if the crashes will still occur.
