Hi, My macos has 4 cores, but i start 3 goroutines, 2 sub goroutines, 1 main goroutine. After main goroutine exec 3 times output, triggering gc causes gcwaiting=1. Finally all goroutine blocking
package main import ( "fmt" "log" "net/http" _ "net/http/pprof" "runtime" // "runtime" "time" ) func deadloop() { for { } } func main() { go func() { log.Println(http.ListenAndServe("localhost:6060", nil)) }() go deadloop() i := 3 for { time.Sleep(time.Second * 1) i-- fmt.Println("I got scheduled!") if i == 0 { runtime.GC() //will set gcwaiting=1, causes other goroutines not to be scheduled } } } -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
