Что значит ошибка goroutine 996 [sleep]:?

Question

[12rbah]

Я запускаю 5 горутин, но при определенных условиях приложение падает примерно с такими ошибками, из особенностей падает тогда когда я быстро запускаю их несколько раз подряд, я думаю что проблема связана с тем, что я неправильно их убиваю, но не уверен.

goroutine 1004 [sleep]:

//ссылки указывают на эту
func skipF(C *Component,skip chan bool){
	for {
		time.Sleep(time.Millisecond*10)
		if C.SkipItem == true{
			C.SkipItem = false
			skip <- false

//и эту горутину
func cancelF(C *appStruct.GuiComponent,cancel chan bool){
	for {
		time.Sleep(time.Millisecond*10)

			cancel <- false
			return

	}

Это функции, а не горутины. И приложите полный текст ошибки.

[12rbah]

Евгений Самсонов, я запускаю эти функции в коде так

go skipF(...)
go cancelF(...)

Верхняя часть ошибки выглядит так, ниже пишет ту ошибку которую сверху написал

Это не ошибка, это стектрейс всех горутин. Sleep означает, что конкретная горутина "спала", ожидала чтения или записи
