openclaw - 💡(How to fix) Fix [Bug]: Gateway memory and connection accumulation over extended runtime on Windows [1 comments, 2 participants]

TL;DR

Implement connection pool management with automatic recycling to mitigate memory and resource accumulation.

Guidance

• Investigate and implement a connection pool management strategy to reduce the accumulation of TIME_WAIT connections, such as using a library like pg with a built-in connection pool or implementing a custom pool with automatic recycling.
• Monitor memory usage and network connections to identify the root cause of the resource accumulation and adjust the connection pool settings accordingly.
• Consider implementing automatic garbage collection triggers to help manage memory usage, but be cautious of potential performance impacts.
• Review the suggested improvements and prioritize implementing a combination of connection pool management, memory usage monitoring, and configurable max memory thresholds.

Example

No specific code example is provided due to the lack of detailed implementation information, but an example of connection pool management using pg might look like:

const { Pool } = require('pg');
const pool = new Pool({
  user: 'username',
  host: 'localhost',
  database: 'database',
  password: 'password',
  max: 20, // max number of connections
  idleTimeoutMillis: 30000, // close idle connections after 30 seconds
});

Notes

The provided guidance is based on the observed behavior and suggested improvements, but the actual implementation may vary depending on the specific requirements and constraints of the OpenClaw Gateway.

Recommendation

Apply a workaround by implementing connection pool management with automatic recycling, as this is a likely cause of the memory and resource accumulation and can help mitigate the issue.
