SignalR存在一個問題（= < v0.5.1），其中請求處於閒置狀態並吸收內存。這似乎已經修正了v0.5.2。但是，可能還有一個額外的問題。SignalR和/或ConcurrentDictionary或SignalR.InMemoryMessage可能發生內存泄漏？
使用WINDBG，我創建了我的新聞傳遞過程的內存轉儲。
首先，這裏是用於SignalR.InMemoryMessage計數和內存消耗：
133099 6388752 System.Collections.Concurrent.ConcurrentDictionary`2+Node[[System.String, mscorlib],[SignalR.Infrastructure.LockedList`1[[System.Action`1[[System.Collections.Generic.IList`1[[SignalR.InMemoryMessage...
最後，這裏有用於頂部3存儲器消耗的對象中的值：執行!dumpheap -mt 000007fef995ae68
000007fef9960bb0 79307 140001536 System.Byte[]
000007fef9956960 1704571 175128912 System.String
000007fef995ae68 1901299 549202440 System.Object[]
，我得到了方法表的一個相當長的概要。大多數物體的尺寸相對較小，這是預期的。然而，在轉儲結束，我看到以下內容：
00000001eb0f3220 000007fef995ae68 160
00000001eb0f3580 000007fef995ae68 40
00000001eb0f35f0 000007fef995ae68 40
00000001eb0f3758 000007fef995ae68 56
00000001eb0f37c8 000007fef995ae68 88
00000001eb0f3820 000007fef995ae68 48
00000001eb0f3cc8 000007fef995ae68 40
00000001eb0f4570 000007fef995ae68 40

00000001eb0f4650 000007fef995ae68 40
00000001eb0f4de8 000007fef995ae68 176
00000001eb0f4ed0 000007fef995ae68 40
00000001eb9b3380 000007fef995ae68 40
00000001eb9b33c0 000007fef995ae68 40
0000000237580080 000007fef995ae68 1146888
於是我繼續前進，做!gcroot 0000000237580080。一些最初的轉儲如下：

在我的申請，我保持的客戶名單中ConcurrentDictionary和刪除客戶端對象如下：
Newsfeed.ClientList.TryRemove(fromHubClient.Key, out newsfeedClient);
我什麼都看不到與wrrong，並看到SignalR.Infrastructure.LockedList 1 [System.Action 1[[System.Collections.Generic.IList 1 [SignalR.InMemoryMessage 1[[System.UInt64, mscorlib]], SignalR]], mscorlib]], mscorlib]], SignalR]
多次提到是否還有與SignalR一些泄漏內存的內存？
