Panic when sending a lot of requests

[AkramHssaini]

I'm currently facing an issue while attempting to handle a considerable number of requests simultaneously. I've observed that my code runs smoothly for the initial half-hour, but subsequently encounters a panic error. Despite experimenting with different configurations for 'maxIdleConnections' and 'maxConnsPerHost,' I have been unsuccessful in resolving the problem. Unfortunately, the application consistently panics after approximately 30 minutes of execution.

I'm sending requests with a "keep-alive" header

client := &fasthttp.Client{
  Dial:                fasthttpproxy.FasthttpHTTPDialerTimeout("user:pass@ip:port", time.Second*15),
  MaxConnsPerHost:     100000,
  MaxIdleConnDuration: 1 * time.Hour
}
