Symptoms</h2> <p>The <code>clw-fs-disconnected</code> error in OpenClaw manifests during runtime when the filesystem service (CLW-FS) loses its connection to the underlying storage backend. Common indicators include:</p> <ul> <li>Console or log output: <code>ERROR: clw-fs-disconnected at fs_core.cpp:145</code>. This logs when the FS service detects a broken pipe or heartbeat failure.</li> <li>Asset loading failures: Game assets (textures, models, levels) fail to load, resulting in black screens, missing textures, or fallback pink checkerboards.</li> <li>Crashes or hangs: On Linux/macOS, segfaults occur due to null pointers from failed FS ops; Windows shows <code>EXCEPTION_ACCESS_VIOLATION</code>.</li> <li>Performance degradation: Repeated reconnection attempts spike CPU usage, leading to frame drops (e.g., from 60 FPS to &lt;20 FPS).</li> <li>Network-related symptoms if using remote FS: High latency (&gt;500ms) or packet loss triggers disconnects in multiplayer setups.</li> </ul> <h2 id="example-log-excerpt">Example log excerpt:</h2> <p>[CLW-FS] Heartbeat timeout after 5s [CLW-FS] Connection to backend lost: clw-fs-disconnected [GameLoop] AssetLoad failed for &rsquo;levels/map1.clw&rsquo;: FS_ERROR_DISCONNECTED</p>
