Frequently Asked Questions

Catalyst server crashes on startup – what to do?

Most common cause: wrong babric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (b1.7.3). You can switch loaders with one click in the panel.

Is Catalyst compatible with babric and bta-babric and fabric?

Catalyst officially supports babric, bta-babric, fabric for Minecraft b1.7.3. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Catalyst – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Catalyst consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
