我正在使用go-json-rest編寫 REST 服務，它反過來使用 net/http。我的服務器代碼很簡單，獲取請求并將其傳遞給通道這是我的服務器代碼package mainimport (    "github.com/ant0ine/go-json-rest/rest"    "log"    "net/http"    "strconv"    "time")const workerCount = 4var evChannel = make(chan Event)var workers = make([]*LogWorker, workerCount)const maxLogFileSize = 100 // In MBconst maxLogFileBackups = 30const maxLogFileAge = 5const logFileName = "/home/sam/tmp/go_logs/event_"func main() {    // Initialize workers    // Four workers is being created    for i := 0; i < workerCount; i++ {        var fileName = logFileName + strconv.Itoa(i)        workers[i] = NewLogWorker(fileName, maxLogFileSize, maxLogFileBackups, maxLogFileAge)        go workers[i].Work(evChannel)    }        // Initialize REST API    api := rest.NewApi()    //api.Use(rest.DefaultDevStack...)    api.Use(rest.DefaultCommonStack...)    router, err := rest.MakeRouter(        rest.Post("/events", StoreEvents),    )    if err != nil {        log.Fatal(err)    }    api.SetApp(router)    log.Fatal(http.ListenAndServe(":4545", api.MakeHandler()))}func StoreEvents(w rest.ResponseWriter, r *rest.Request) {    event := Event{}    err := r.DecodeJsonPayload(&event)    if err != nil {        rest.Error(w, err.Error(), http.StatusInternalServerError)        return    }    // TODO : Add validation if needed    // Add code to parse the request and add further information to event     // log.Println()    select {        case evChannel <- event:        case <- time.After(5 * time.Second):      // throw away the message, so sad    }        // evChannel <- event    //log.Println(Csv(event))    w.WriteHeader(http.StatusOK)}當我使用 jmeter 連續執行它時，我偶爾會收到以下錯誤http: 接受錯誤：接受 tcp [::]:4545: 打開的文件太多；10ms 后重試net/http 是否為每個請求打開文件？
