Root Cause

The HTTP client has reached the maximum number of idle connections and cannot create new ones due to limits.

generic

中文

HTTP客户端达到最大空闲连接数，因限制无法创建新连接。

Workarounds

  1. 90% success 
    Use http.Transport with appropriate MaxIdleConns and MaxIdleConnsPerHost settings
  2. 85% success 
    Implement connection pooling with a worker pool to limit concurrency

Dead Ends

Common approaches that don't work:

  1. 50% fail

    May still hit OS file descriptor limits

  2. 40% fail

    Increases latency and connection overhead
