How to Fix Palworld Dedicated Server Memory Leaks & Lag
Key Takeaways & Summary
Learn why Palworld dedicated servers experience severe memory leakage and lag over time, and how to configure automated scheduled reboots, RCON saves, and optimizations.
How to Fix Palworld Dedicated Server Memory Leaks & Lag
Hosting a dedicated server for Palworld is a fantastic way to enjoy the game with friends, but many server hosts eventually run into severe lag, rubber-banding, or server crashes.
The main culprit? Memory leaks.
In this guide, we will analyze why these memory leaks occur and how to use Palworld Server Manager (PSM) to mitigate them completely.

What Causes the Palworld Server Memory Leak?
Palworld's dedicated server binary files have engine-level bugs where memory allocated to loading Pal assets, structures, and player positions is not garbage collected properly when players log out or move to different areas.
As a result:

3 Steps to Solve Palworld Server Lag
1. Implement Scheduled RCON Auto-Restarts
The most effective way to handle memory leak issues is to schedule a graceful restart of the server every 12 or 24 hours.
Using PSM, you can automate this in three steps:
/Broadcast Server_reboot_in_60_seconds! /Save command via RCON, terminate the server cleanly, flush system caches, and restart it in under 10 seconds.2. Configure CPU Thread Affinity
By default, Windows distributes threads across cores dynamically. For a high-performance game server, this switching can cause micro-stutters.
Within PSM, go to Performance Settings and bind the Palworld dedicated server process to specific high-performance CPU cores.
3. Lower Drop Item Limits
Every item dropped on the ground in Palworld is tracked by the server database. If players leave hundreds of items scattered around bases, server tick-rate drops.
Open the Config Editor in PSM, navigate to gameplay settings, and set DropItemMaxNum to a lower value (e.g., 1000 instead of the default 3000) to keep tick-rates high.
