Q100432: Nuke crashing with 'Assertion Failed' error message


Several users have reported seemingly random crashes in Nuke on Windows 7 and 10, with an error message in the terminal similar to the following:
Assertion failed: Address already in use (..\..\..\src\signaler.cpp:310)
The crash occurs during normal use of Nuke without any deliberate actions from the user. This issue has been reproduced internally on both Windows 7 and 10.


The crash seems to be caused due to a compatibility issue between Nuke and the specific build of Windows, which from our internal testing seems to be OS Build 17134.165 for Windows 10.


Internally we were able to resolve this issue by installing the latest Windows updates. This has been supported by reports from users who are no longer experiencing the crash after installing the latest updates. 

For more information on how to manually scan for and install Windows updates, please refer to the this page on Microsoft's website.



If installing the latest Windows updates does not resolve your issue, please open a Support ticket and let us know the exact version of Nuke and the exact build of Windows that you are using and the troubleshooting steps you have taken so far.

To check for your current Windows build, press the Windows Key + R and type winver into the dialog box that appears. A window similar to the following should now be displayed:
