I have an odd issue with my implementation of Rebus which has been working for the past couple of years without any issue, and I am trying to figure out the scope of the problem and where to focus my troubleshooting effort. A little context:
We have been running version 0.99.66
Moved to version 3.1.5 last week, then saw the issues appear
Rolled back to 0.99.66, issues continue
Using MSMQ for the transport
Running Windows Server 2016
Identical code running on other server instances without issue
So, we are experiencing seemingly random instances where messages are failing, ending up in the error queue with a Rebus error saying that the message could not be dispatched to any handlers. This could happen once, but then when an identical message type comes through the next time, it gets handled correctly.
Here is a snippet of the code in question:
public class ProcessManagerService
{
public ProcessManagerService()
{
...
BusAdapter = new BuiltinHandlerActivator();
BusAdapter.Handle<FileEventMessage>(async msg => await StartProcess(msg));
BusAdapter.Handle<ProcessRequest>(async msg => await StartProcess(msg));
Bus = Configure.With(BusAdapter)
.Logging(l => l.ColoredConsole(LogLevel.Error))
.Transport(t => t.UseMsmq(ConfigurationManager.AppSettings["Queue"]))
.Start();
}
...
public async Task StartProcess(FileEventMessage msg)
{
var svc = new StepManager() { FileEvent = msg.FileEvent };
await svc.Run();
}
public async Task StartProcess(ProcessRequest msg)
{
var svc = new StepManager();
await svc.Run(msg);
}
}
And here is an example of the exception that is thrown:
5 unhandled exceptions: 12/18/2018 7:53:00 AM -06:00:

Assuming the obvious and that it is something in this particular server instance/enviornment, I am trying to figure out why Rebus is behaving this way, and what in my environment may be causing this. Any direction as to where to start looking would be greatly appreciated!
Sounds pretty weird :) when people have this problem, it's almost always because they have somehow set up multiple Rebus instances to consume messages off of the same queue.
In some rare cases, it's because .Start() is called on the bus before handlers are added to the container/built-in handler activator, but that doesn't seem to be the problem in your case.
Can you tell me more about your setup? If it's about as simple as what you're showing above, maybe you can reproduce it in a separate application?

I am having problems getting the dotnet graph sdk to use my proxy settings as expected. I have tried setting the proxy when initializing the HttpClient with the GraphClientFactory but still seem to get the exception I am showing below. These same settings are being passed to the ConfidentialClientApplicationBuilder and is being used to succsesfully request the authentication token. It is also communicating to internal application API's through the same proxy settings with no problems. Can someone please help point me in the right direction? I am using the most recent version of the Graph SDK 4.36.0.0
public async Task Initialize(WebProxy webProxy)
{
var httpClientFactory = new GraphIntegrationHttpClientFactory(webProxy);
IConfidentialClientApplication daemonClient;
//Creates a daemon service.
daemonClient = ConfidentialClientApplicationBuilder.Create(_clientId)
.WithAuthority(string.Format(Constants.AuthorityFormat, _tenantId))
.WithClientSecret(_clientSecret)
.WithHttpClientFactory(httpClientFactory)
.Build();
//Gets auth token.
AuthenticationResult authResult = await daemonClient.AcquireTokenForClient(new string[] { Constants.MsGraphScope })
.ExecuteAsync();
ClientCredentialProvider authProvider = new ClientCredentialProvider(daemonClient);
var handlers = GraphClientFactory.CreateDefaultHandlers(authProvider);
handlers.Add(new LoggingHandler(_logService));
var httpClient = GraphClientFactory.Create(handlers, proxy: webProxy);
httpClient.Timeout = TimeSpan.FromMinutes(5);
_graphServiceClient = new GraphServiceClient(httpClient);
}

I have found a way to get around this problem, by passing a customer HttpClientHandler with all the information set as the finalhandler parameter for the GraphClientFactory Create method. I have opened a new issue on the github page about passing the proxy not working properly.
I am using Magento.RestApi in a larger system, where I load the code dynamically from a DLL.
When I use the below code in a stand-alone project, it works fine:
private async void dostuff() {
var client = new MagentoApi()
.Initialize("<url>", "key", "secret")
.AuthenticateAdmin("user", "pass");
var response = await client.GetProductBySku("sku");
// The response contains the result or errors
if (!response.HasErrors) {
var product = response.Result;
... do stuff with the result ...
}
}
But, when loaded in the larger project, I get "The request was not successfully completed.", also when trying to catch the error to find the InnerException or the stack trace, the debugger doesn't seem to work anymore. Printing out the stack trace gives me:

I had to compile the Magento.RestApi from source, as the NuGet package uses a different NewtonSoft.Json package than my large project. This works fine in the stand alone version.
I've created a graph in CosmosDB with two vertex types, an actor vertex and a movie vertex. The only edge type that exists is an "acted in" type. You can imagine the graph as having many actors and many movies and any given actor may have acted in any number of movies.
I am trying to write a query that will discover and return the path between two actors. For example, Keanu Reeves acted in the Matrix with Laurence Fishburn. Laurence Fishburn acted in the movie Apocalypse Now with Marlon Brando. Therefore, the path between Keanu Reeves and Marlon Brando is Keanu Reeves -> The Matrix -> Laurence Fishburn -> Apocalypse Now -> Marlon Brando.
This is the query that I've come up with.
g.V('keanureeves')
.repeat(both().simplePath())
.until(hasId('marlonbrando'))
.path()
.limit(1)
The query works for small graphs. I can query and construct the path. However, once I get to a certain graph size, the query times out and never finishes.
I am using the CosmosDB emulator locally, not the real CosmosDB on Azure. It's hard to say how many documents are in the database because the emulator UI doesn't give me a way to query for a count.
Can I speed up my query without changing my data model? If I do have to change my data model, what might work better? I'm new to graph databases and Gremlin.
Edit: It seems to happen between 1200 and 1300 documents. Under 1200 documents, results return. Here's the breakdown of document types:
540 movie vertexes
112 actor vertexes
681 actedIn edges
Edit #2: I'm using the Microsoft.Azure.Graphs NuGet package and it looks like the method I'm invoking is throwing an OutOfMemory exception. My code:
public async Task<IList<T>> ExecuteQueryAsync<T>(string gremlinQuery)
{
var query = _documentClient.CreateGremlinQuery(_graph, gremlinQuery);
var results = new List<T>();
while (query.HasMoreResults)
{
var feed = await query.ExecuteNextAsync<T>();
results.AddRange(feed.Select(x => x));
}
return results;
}

How can I handle and ignore these exceptions by exception filter? Why this error occurs and how can I reproduce that? I wanna catch and ignore only The client disconnected but not all HttpException
I saw this similar question but how can I do that in exception filter?
You can ignore these exceptions.
The exception says what the problem is: "The client disconnected". It means that the client initiated a request but then disconnected before it bothered to read all of the response.
There are any numbers of reasons why that might be the case, but (unless you have a dodgy internet connection at your server end) it is almost certainly an issue at the client end. I regularly see these myself and mostly it seems to be related to a bot. So I filter them out and ignore them.
try
{
// Open Connection
// Do stuff
}
catch (HttpException ex)
{
// Log it?
// Ignore it?
// Do what you want with it?
}
finally
{
// Close connection

Our company is using OWIN with ASP.NET MVC 5 and one of our developers is getting the following stacktrace at seemingly random times; however, I cannot reproduce the issue. I'm using SimpleInjector, but don't think this is related to it even though that line 118 in the stacktrace is the following:
app.Use(async (context, next) => {
using (container.BeginExecutionContextScope())
{
await next();
}
});
The other suspicious part is the reference to this in the stacktrace
Microsoft.Owin.Mapping.MapWhenMiddleware
I have a MapWhen configured like this
app.MapWhen(c => c.Request.Path.StartsWithSegments(new PathString("/api/mobile")),
api =>
{
ConfigureBearerApps(api, ValidateMobileIdentity);
});
StackTrace:
System.ObjectDisposedException: Cannot access a disposed object.

Is there any additional logging I can enable to find the cause?
Most likely, you've implemented IDisposable on the object you're injecting, and then somewhere, you're calling Dispose on it. When using dependency injection, the container owns the instance and is responsible for disposing of it. The code you've posted doesn't provide any guidance as to where this might be occuring, so I would simply do a search for Dispose in your project and step through the results until you find something suspicious.
