[英]Memory leak in F# async recursive call
I'm confused why this function shows memory constantly increasing 我很困惑为什么此功能显示内存不断增加
let rec startRead1() =
async {
do! Async.Sleep 1
System.GC.Collect()
let mem = System.GC.GetTotalMemory(true)
printfn "%d" mem
do! startRead1()
}

[<EntryPoint>]
let main _ =
startRead1() |> Async.RunSynchronously
0
Whereas this one shows stable memory 而这个显示稳定的记忆
let rec startRead2() =
async {
while true do
do! Async.Sleep 1
System.GC.Collect()
let mem = System.GC.GetTotalMemory(true)
printfn "%d" mem
}
The synchronous version is stable too. 同步版本也很稳定。
let rec startRead3() =
System.Threading.Thread.Sleep 1
System.GC.Collect()
let mem = System.GC.GetTotalMemory(true)
printfn "%d" mem
startRead3()
