hang

I am trying to run MSBuild on my (mostly C++) projects (imagine a really humongous code base). Visual Studio 2015 is the toolset in question ( Windows 7 SP1 and VS 2015 Update 2 ). Even with /m:1 (and thereby forcing it to use only one processor) I am finding some completely random project constantly hanging at the compile phase. For example, when this issue happens, if I look at the offending project and the files it comprises of, I can see that the .obj files have been created successfully for every translation unit. However the system just never moves on to the link phase. I see two

I have a LWJGL program (LWJGL 2.9.0) that sometimes randomly hangs. The problem with debugging it is that mouse is always grabbed. On Windows it's possible to get mouse back without any issues, but on linux (I use linux Kubuntu) the only way I know to get mouse back is to stop the application. The same issue happens when a breakpoint hits when mouse is grabbed. Using netbeans debug mode I can pause application and get some information at any time, but when the application hangs mouse no longer works (there is no cursor). Is it possible to get the mouse back without stopping the application or

I am running an app in Play using activator run , and maybe 3 out of 5 times, it will just hang, when I go to http://localhost:9000/ , it just sits there spinning forever. I'm seeing a lot of promise timed out errors also. Where should I look for this issue? I turned up logging with logLevel := Level.Debug , but I see nothing amiss. While the app is spinning, I see no logging at all. If I just let it sit and spin for a long time (~5 min) it will eventually give this error: [info] play.api.http.HttpErrorHandlerExceptions$$anon$1: Execution exception[[PrivilegedActionException: null]] [info] at

Having a problem with Eclipse (Luna) IDE, while running the program I encountered a never ending loop so had to terminate the program. After which every-time I try to re-run the program it just hangs when loading the Debug Configuration. I am trying to create a Eclipse Plug-in to retrieve a file name and add comments to it. I don't believe there's an error with the program as it was working fine before. I have tested a simple helloWorld program in another workspace to see if there were any problems but that program works fine. From what I have read it could be something to do with the metadata

i've recently encountered a problem trying to share large data among several processors using the command 'send' from the mpi4py-library. Even a 1000x3 numpy float array is too large to be sent. Any ideas how to overcome this problem? thx in advance. I've found a simple solution. Divide data into small enough chunks... I encountered this same problem with Isend (not with Send ). It appears that the problem was due to the sending process terminating before the receiver had received the data. I fixed this by including a comm.barrier() call at the end of each of the processes. Point-to-point send

In the 'old' times it was very easy to track which method is hanging: just go to debugger, hit 'pause' button and go through stack traces. Now however, if the problem is in the async method, this approach does not work - since the next piece of code to execute is buried somewhere in the continuation tasks (technically it does not even hang)... Is there a way for such easy debugging with tasks? UPD. Example: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); } private async void MainWindow_OnLoaded(object sender, RoutedEventArgs e) { await DoHolyWar();

All , I create : public static final HttpClient DEFAULT_HTTPCLIENT = HttpClients .createDefault(); for(int i=0 ; i<5; i++){ DEFAULT_HTTPCLIENT.execute(requests[i]); } But when loop is to i =2 , that means just execute first two request , till third request , the client will hang and seems dead loop . I refer some materials , I got may be caused by Http Thread Pool configuration limited . But I know what is standard solutions for this issue ? Since I want to send any request any times, but I don't want each time to create new HttpClient . So Do you have any good and standard suggestions for

I am currently having some trouble with a process that is hanging. First of all, the below thread dump shows no deadlock. Another interesting thing is that the process is hanging at java.lang.System.identityHashCode method. The currently CPU usage of that process is 0%, sometimes peaks at 1%... normally the process uses 100%. It is using 1.7GB of RAM (which is normal for this process). The machine has plenty of CPUs, disk space and RAM available. Attaching to process ID 4146, please wait... Debugger attached successfully. Server compiler detected. JVM version is 23.7-b01 Deadlock Detection: No
