QThread::start: Failed to create thread (The access code is invalid.) terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

Dear All,
i am having program crashed with message :
- QThread::start: Failed to create thread (The access code is invalid.)
- terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc
- This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information
Please kindly advise me, is it caused by Operating System Windows 2016 (that i am using) or caused by the QT Compiler not compatible or coding issue ?
thank you for your kind attention.
best regards,

Use a debugger, take a look at the backtrace where it crashes and why.
-
@Christian-Ehrlicher : actually i am the end-user of the application. My developer said it is caused by my server's Operating System Windows 2016 that causee his program crashed and displaying the messages i mentioned above
-
But what should we do against this then?
-
@Christian-Ehrlicher : if from your view, based on your long experiences, may i know is it caused by Operating System Windows 2016 (that i am using) or caused by the QT Compiler not compatible or coding issue ?
-
It can be all of them. Since Windows Server 2016 is based on Win10 I doubt it's an OS issue. The only way to find it out is to debug the crash.

@Christian-Ehrlicher : oh i see, many many thanks for your view and feedback , really appreciated. Let me once again check with them. By the way, anybody here in the Forum feel free to give your feedback or comments, thank you for all your kind attention

Hi,
In addition to @Christian-Ehrlicher, are you running a 32 or 64bit version of the OS ? What about the application ?
One of the reasons for that error to be thrown is memory exhaustion but it's not the only one. See here.

Did you check your RAM hardware health ?

@Dunant
I don't think @SGaist [please correct me if I have misinterpreted] is asking you to report how much RAM you have, he is asking to "check your RAM hardware health". I read that as run a physical hardware memory checker. I don't know why he suspects that from the output you showed, but he usually knows what he is talking about.... -
since 29 March 2021 until today (already 7 months), the application not crashing anymore due to every midnight i did restart the operating system Windows Server 2016.
Today i just had meeting with our vendor, the vendor still saying nothing wrong with the application , not admitting their application that caused the crash problem, and blame our server's operating system that having problem. I am not programmer/developer so i have nothing to say. At the end of the discussion, our vendor informing us to use Linux Red Hat operating system which they claimed no issue. I will discuss internally about this.
