How to Fix a Farming Valley Server That Keeps Crashing
Farming Valley is a Stardew Valley and Harvest Moon-inspired pack on Forge 1.10.2 with over 3 million downloads — a gentle farming-and-community loop rather than combat or heavy automation. That older Forge version brings its own quirks, and the pack's NPC romance system adds a failure mode most newer packs don't have. Here's how to work through the most common crash causes.
See the Farming Valley pack page for the full RAM and setup breakdown before you chase anything else.
1. Wrong Java version (the most common instant-crash cause)
Forge 1.10.2 is an older build that requires Java 8 to run reliably. If your server environment defaults to a newer Java runtime — which is increasingly common on fresh systems and some hosting panels — Forge can fail to initialize, throw class-loading errors, or crash immediately on startup before you even see the world load.
- Check the Java version your server is actually launching with, not just what's installed on the machine
- If you've recently moved to a new host or rebuilt the server, this is the first thing to verify
2. Unclean shutdowns corrupting NPC relationship data
Farming Valley's romance and relationship system tracks ongoing state for every player's interactions with NPCs. That data gets written to disk periodically and on save — if the server process is force-killed mid-write rather than stopped gracefully, the save can end up partially written.
The symptom usually isn't an immediate crash. It's often a crash or repeated error a session or two later, once the game tries to read the now-corrupted relationship data back in.
3. Older pack, newer filesystem/OS quirks
Being a 1.10.2-era pack, Farming Valley was built against assumptions about the environment that are a few years old at this point. Running it on a modern OS or filesystem usually works fine, but it's a pack where small environmental mismatches are more likely to surface as odd, hard-to-pin-down crashes than on a recently-built modpack. If a crash doesn't match a clear mod or config cause, don't rule this out.
4. Config or save corruption from a bad edit
If you've hand-edited a config file or manually touched save data while troubleshooting something else, a malformed edit can produce a crash that looks unrelated to what you changed. Revert any manual edits you're unsure about and test again before assuming the problem lies elsewhere.
5. RAM under the pack's realistic floor
4 GB is the real floor for Farming Valley. Under-provisioning rarely shows up as a single clean crash — it usually looks like gradual lag and garbage-collection pauses that get worse over a session, eventually ending in a tick timeout or a hard stall rather than an instant out-of-memory error. If your server has been getting slower the longer it stays up, check allocated RAM before anything else.
FAQ
Why won't my Farming Valley server start at all?+
The most common cause on a Forge 1.10.2 pack like Farming Valley is running the wrong Java version. This era of Forge needs Java 8 — if your host or machine defaults to Java 11, 17, or 21, Forge will typically fail during startup or throw mod-loading errors before the world ever loads. Check your server's configured Java version first, before looking at mods or configs.
Can stopping the server crash it later?+
Yes, and it's one of the sneakier causes with this pack. Farming Valley's NPC romance and relationship system stores a lot of per-player state, and if the server process is force-killed instead of shut down gracefully (via the console stop command or a proper panel stop), that data can be mid-write when the process dies. The server might boot fine next time, then crash or throw errors once it tries to load the corrupted relationship data. Always stop cleanly, and keep a recent backup before any restart you're not sure about.
How much RAM does a Farming Valley server actually need?+
4 GB is the real floor for Farming Valley in practice. It's a gentler, less automation-heavy pack than most modern tech packs, so it doesn't need the 8-10 GB you'd allocate to a heavier modern Forge pack — but going under 4 GB on a pack this old, running on modern hardware, tends to produce slow degradation (lag, GC pauses) rather than a clean out-of-memory crash.
Host Farming Valley on hardware sized for its real floor
Run Farming Valley on a server provisioned for its real 4 GB floor, and take a backup before any risky change — especially before a force-stop or manual save edit.
