Azure EventHub Absender nicht zum Senden von Nachrichten

Question

I neuestes WindowsAzure.ServiceBus nuget Paket und einfachen Code-Snippet verwenden, um Nachrichten zu Azure EventHub von meiner Cloud Service WebRole api Controller senden:

var eventData = new EventData(buffer) { PartitionKey = partition }; 
await _eventHubClient.SendAsync(eventData); 

Nach einer Weile nicht Absender Nachrichten senden und ich sehe folgende Ausnahmen in Protokollen jedes Mal, wenn ich versuche, eine Nachricht zu senden:

Microsoft.ServiceBus.Messaging.MessagingCommunicationException:

Scheint einmal Sender stolpern auf diesem Fehler kann es keine Nachrichten mehr senden.

Answer 1

Fehlercode 0xE ist ERROR_OUTOFMEMORY von der Ablaufverfolgung. Als Workaround können Sie entweder die Webrolleninstanz vergrößern oder die Ablaufverfolgung vollständig deaktivieren.

Ich habe einen Fehler, um dies auf unserem Client zu beheben. Grundsätzlich sollten Messaging-Operationen aufgrund von Trace-Problemen nicht fehlschlagen.
