Hi,

I noticed this since about 2 weeks ago.

When a solution is just started, everything is OK. But after I worked on the solution for about 30~90 minutes, I begin experience the following issue:

1. In the NCrunch Tests window, double click a test to open a test file.
2. The UI will freeze for about 2 minutes.
3. Double click any other tests, the test files will be opened immediately.
4. Close all opened test files.
5. Repeat step 1, the UI will freeze another 2 minutes.

Restarting the solution fix the issue for another 30~90minutes.

I tried to reproduce this in a new project, but no success. I'm experiencing this issue with all my major solutions (they share a common library).

I tried to uninstall NCrunch, run devenv.exe /setup, then reinstall NCrunch, but no success.

NCrunch 1.45.0.12
Visual Studio 2012 with Update 2
Windows 8 64bit

Regards,
Yang

Hi Yang,

Do you notice any patterns around memory utilisation or NCrunch when this happens? I.e. do you have a full test pipeline at the time?

Are you making use of any source files that exist on shared network resources? i.e. mapped network drives?

Does attempting to open a new source file using project explorer also create the same behaviour when this has started happening?

I'm wondering if it might be a possible to obtain a dump of the executing threads within VS when the pause locks in. Would it be possible for you to try the following steps?

1. Wait until the problem starts appearing
2. Load up a second instance of Visual Studio
3. Attach the debugger from the second instance of VS onto the first (bugging) instance of VS
4. Break into the process using the debugger
5. Open up the list of threads
6. Copy/paste the output of running threads here into the forum

.. This will help with identifying where the UI thread is being locked, and who is locking it!


Cheers,

Remco

Memory utilization seems to be normal (NCrunch < 100 MB, devenv.exe < 1000MB).

When the issue happens, NCrunch's CPU usage is < 1%, while devenv.exe ~ 25% (4 core CPU).

Nope, most of the time I don't have any pending tests when the issue happens.

No, I don't have any shared network resources / mapped network drives on this machine. All source code resides on SSD.

No problem with Project Explorer.

Thanks Yang, that helps a lot! This line catches my attention:

Not Flagged 5044 1 Main Thread Main Thread System.Array.Copy() Normal

This would be the direct cause of the problem. The next time this happens, is there any chance you could grab a stack trace for this specific thread? If we can see what is causing the copying of what is probably a very large array, we'll be able to narrow this right down.

Sorry for my late replay. I tried multiple times to capture the stack trace of the main thread when the issue happens. But didn't catch the System.Array.Copy() again.

Today the symptom is not as bad as before, but still takes 30+ seconds to open a test file when issue happens.

Thanks Yang. Sadly this hasn't given us a smoking gun pointing at the problem, but it does narrow things down somewhat.

When NCrunch tries to navigate to a document, it relies on a set of VS automation interfaces to pull up the list of documents and open the relevant document. Control then passes to the underlying API where Visual Studio works its magic. This means that the lockup isn't caused by NCrunch directly, but instead is triggered indirectly (i.e. VS is locking up in response to an API call that it should reasonably be able to handle without locking up).

Of particular interest to me in the stack trace is this component: AxTools.VS10X.CodeMap.dll

It looks as though the component (a VS plugin/package?) is performing a major visual refresh in response to either the navigation instruction, or the document query. Is this a plugin you've installed yourself that you may be able to disable? Doing so could help narrow down what is happening here ... it looks as though this may be a performance issue with the plugin that NCrunch is surfacing.

Something else that might be helpful is to try breaking into the process several times while it is locked up, and to see if the stack traces are in rough alignment between each break. This will help to identify whether the issue is coming from one place, or many.

Cheers,

Remco

AxTools.VS10X.CodeMap.dll belongs to VS10x Code Map.

That could be the source of the problem, it displays a code map for a document when its opened. Maybe its recent update causes the problem (I get an update every 1~3 weeks). I will try to disable it temporarily and will post here when I have more info.

Cheers,
Yang

Have not experienced this issue since disabled VS10X Code Map 2 days ago. I will raise a bug with them.
