openclaw - 💡(How to fix) Fix [Bug]: The tasks in ./openclaw/jobs.json cause the WebUI to crash. [2 comments, 2 participants]

1.When configuring a scheduled task, an error is reported immediately.

Fix Plan

To resolve the issue, we need to optimize the memory usage of the gateway process when handling the jobs.json configuration.

• Step 1: Optimize Configuration Loading
  • Modify the configuration loading mechanism to load jobs.json in chunks or lazily, rather than loading the entire file into memory at once.
  • Example (in JavaScript):

const fs = require('fs'); const readline = require('readline');

// Load jobs.json in chunks const fileStream = fs.createReadStream('jobs.json'); const rl = readline.createInterface({ input: fileStream, crlfDelay: Infinity });

let chunk = ''; rl.on('line', (line) => { chunk += line; // Process the chunk console.log(chunk); chunk = ''; });

*   **Step 2: Implement Memory Monitoring**
    *   Monitor the memory usage of the gateway process and restart it when memory usage exceeds a certain threshold.
    *   Example (in JavaScript using `node-os-utils`):
        ```javascript
const osUtils = require('node-os-utils');

// Monitor memory usage
osUtils.memInfo().then((info) => {
  if (info.usedMemPercent > 80) {
    // Restart the process
    console.log('Memory usage exceeded threshold. Restarting...');
    process.exit(1);
  }
});

• Step 3: Clear jobs.json on Restart
  • Clear the jobs.json file when the gateway process restarts to prevent memory issues.
  • Example (in JavaScript using fs):

const fs = require('fs');

// Clear jobs.json on restart fs.writeFile('jobs.json', '', (err) => { if (err) { console.error('Error clearing jobs.json:', err); } else { console.log('jobs.json cleared.'); } });

### Verification
To verify that the fix worked, restart the gateway process and monitor its memory usage. The process should no longer consume excessive memory, and the `jobs.json` file should be cleared on restart.

### Extra Tips
*   Regularly clean up the `jobs.json` file to prevent it from growing indefinitely.
*   Consider implementing a more efficient data storage solution, such as a database, to replace the `jobs.json` file.
*   Monitor the gateway process's memory usage and adjust the threshold value as needed to prevent unnecessary restarts.
