Fix clw-memory-not-found: Memory object not found in OpenClaw runtime

Fri, 17 Apr 2026 06:24:49 +0800

1. Symptoms

The clw-memory-not-found error manifests in OpenClaw, the open-source reimplementation of the Claw game engine, during runtime when the engine attempts to access a memory object by its handle (ID) that no longer exists or was never allocated. This is common in custom mods, level editors, or extended gameplay logic where developers interact with the engine’s memory management API.

Typical symptoms include:


CLW_ERROR: clw-memory-not-found: Memory block ID 0x1A2B3C4D not found in allocator registry.
Stack trace:
 clwMemoryGetPointer() at memory.c:145
 levelLoadAssets() at level.c:278
 gameLoop() at main.c:512
Aborting due to invalid memory access.

Console/Log Output: Immediate crash with the above error format. The ID (e.g., 0x1A2B3C4D) is the hexadecimal handle of the missing memory block.
Game Behavior:
- Sudden termination during level loading, asset streaming, or save state restoration.
- Black screen or frozen frame if running in a debugger.
- On Windows, a dialog box: “OpenClaw has stopped working.”

Performance Indicators:

[DEBUG] Memory registry size: 128 blocks
[DEBUG] Lookup for ID 0x1A2B3C4D: MISS
[FATAL] clw-memory-not-found triggered.

Frequency: High in modded builds or when integrating third-party assets. Seen across platforms, but more prevalent on Linux due to stricter ASLR (Address Space Layout Randomization).

This error halts execution to prevent buffer overflows or use-after-free exploits, a deliberate safety feature in OpenClaw’s clw_memory.h module.
