hang

I have previously used virtualenv with no problems under Python 2.7 and 3.5. Recently, I tried to create a new virtualenv and found that calling pip list caused an indefinite hang. Calling any executable .exe in the virtualenv's scripts folder EXCEPT python causes an indefinite hang, which: can be broken out of by raising a KeyboardInterrupt (Ctrl-C), but provides no traceback (indicating that python has not yet started running the script?) but cannot be killed by "End Proccess" in the Task Manager How do I even start to go about troubleshooting this? So far I have tried: Successfully

I have a web application which uses jQuery/JavaScript heavily. It holds a large array in memory, and the user filters it by typing in a textbox. Problem: When the filtering algorithm runs, the application becomes non-responsive and the browser may even ask the user whether to let the script continue. Optimally, I would like the filter function to run in a separate thread , to avoid non-responsiveness. Is this possible in any way? Alternatively, I would like to show a rotating hourglass or similar, but browsers seem unable to display animated GIFs when running heavy scripts. What is the best

I've been using the Java Service wrapper in a custom application for quite a while and it's been working fine. Since updating our application to a new version in the last few days the JVM started hanging and then wrapper prints this in the log: JVM appears hung: Timed out waiting for signal from JVM. It then automatically terminates the JVM and starts the app again. This happens after about 10 hours of running, which just makes it harder to debug. Of course I am going to look through the changes that we've made, but no major changes were made that I would suspect is causing this type of

I'm using PyDev in Eclipse as my Python editor. It's fine in terms of feature set. Everything works fine except for one very annoying thing: Code completion itself works fast. When I press Alt+Space, the window pops out almost instantly and all the options are there. The option at the top is selected. Then comes the trouble . The detailed description won't appear until about 5-10 seconds. All this time CPU is working at maximum load and the interface is not responding. All the processor is consumed by the Eclipse Java process (the spawned Python process seems idle). Then a yellow window pops

My PC hangs when I send key in Form_Shown() and placing Breakpoint at Form_KeyDown() private void Form1_KeyDown(object sender, KeyEventArgs e) { //breakpoint here if (e.KeyCode == Keys.A) { MessageBox.Show("caught"); } } private void Form1_Shown(object sender, EventArgs e) { SendKeys.Send("A"); } I repro, Win7 and VS2008. That looks like a fairly nasty deadlock, you can get out of it by pressing Ctrl+Esc on the keyboard. By default, SendKeys uses a windows hook to inject the keys. Windows hooks can have fairly unpleasant side effects but I wouldn't hesitate to call this a Windows bug. To fix

Under heavy load or when using jQuery's ajax abort function, we see requests build up in IIS to the point where no-one can connect and the entire site hangs, forcing a recycle. A similar post from 3 years ago had a similar issue with .NET 4.5 and IIS 7.5 but Microsoft have stated this was fixed in 4.5.1 and released a patch for 4.5. This problem on Windows Server 2012R2 using IIS 8 when trying to use State Server and even more so when using State Server on development machines running Windows 10 and IIS10. The patch cannot be installed on any of these machines as the installer is blocked by

Our program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete) . Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed. (Example of application freezing - the mountains are from my desktop background) If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted. It's
