[Bug]: 产生数据竞争

Actions I've taken before I'm here

• I've thoroughly read the documentations on this issue but still have no clue.
• I've searched the Github Issues but didn't find any duplicate issues that have been resolved.
• I've searched the internet for this issue but didn't find anything helpful.

What happened?

当在两个goroutine里调用gnet.Run()时，gnet.Run()函数内的logger产生数据竞争.
因为我需要在一个程序里用两个端口提供各自不同的服务，所以启用了两个gnet服务，产生上述问题。

Major version of gnet

v2

Specific version of gnet

v2.3.0

Operating system

macOS

OS version

Darwin 22.3.0 x86_64

Go version

go1.20

Code snippets (optional)

go func() {
		
		err := gnet.Run(cServer, cServer.addr, options...)
		if err != nil {
			log.Errorf("gnet.Run() erro:%v", err)
			os.Exit(1)
		}
	}()

        go func() {
		
		err := gnet.Run(gServer, gServer.addr, options...)
		if err != nil {
			log.Errorf("gnet.Run() erro:%v", err)
			os.Exit(1)
		}
	}()

How to Reproduce

1.将gnet.Run()放在两个goroutine中
2.每个gnet.Run监听不同的端口
3.启动程序
4. go run -race main.go 产生竞争输出
