Frequently Asked Questions
OptimVanilla server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a OptimVanilla server really need?
Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).
Can I add custom mods to OptimVanilla without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
OptimVanilla server lagging – performance tips
1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time.
