    Hi,

    I have created qt qml application on ubantu (legacy kernel) with qt5.4. I am using this application as on boot application, for this I have created .application file which calls this application . This app uses serial ports of board, controls some gpios by calling python file . I have used multi threading using QThread as I wanted thread to be permanent and signal slot method to communicate with qml . This application is working fine but it crashes after 2- 2 and half hrs.The application output console gives no error message after crashing, so i am not able to find the exact reason for crashing.

    Can anyone help me with this? This is critical for me , I want this application to run till I stop it

    Regards

      I have a multithreaded Qml application that uses both networking and serial port. This app works 24 / 24 and 7 / 7 days without any problem.
      I suggest you to run your application in a developing machine in debug mode to resolve all the bugs.
