C Runtime Error R6016

  • Artikkeli

not enough space for thread data

Note

If you encounter this error message while running an app, the app was shut down because it has an internal memory problem. There are many possible reasons for this error, but often it's caused by an extremely low memory condition, a bug in the app, or by a bug in an add-in or extension used by the app.

You can try these steps to fix this error:

  • Close other running applications or restart your computer to free up memory.
  • Use the Apps and Features or Programs and Features page in the Control Panel to repair or reinstall the app.
  • Use the Apps and Features or Programs and Features page in the Control Panel to remove, repair or reinstall add-ins or extensions used by the app.
  • Check Windows Update in the Control Panel for software updates.
  • Check for an updated version of the app. Contact the app vendor if the problem persists.

Information for Programmers

This error occurs because the program did not receive enough memory from the operating system to complete a _beginthread or _beginthreadex call, or thread local storage has not been initialized by _beginthread or _beginthreadex.

When a new thread is started, the library must create an internal database for the thread. If the database cannot be expanded by using memory provided by the operating system, the thread does not begin and the calling process stops. This can happen when too many threads have been created by the process, or if thread local storage has been exhausted.

We recommend that an executable that calls the C runtime library (CRT) should use _beginthreadex for thread creation rather than the Windows API CreateThread. _beginthreadex initializes internal static storage used by many CRT functions in thread local storage. If you use CreateThread to create a thread, the CRT may terminate the process with R6016 when a call is made to a CRT function that requires initialized internal static storage.
