set as detached.During the termination,there are
few threads which shows its state as joinable and are not
getting completely cleaned up.

The threads marked as detached are getting modified as
joinable.

  • Workaround:
Create the thread in detached state, instead of setting
the state later using the pthread_detach() routine.

  • The detached threads in threaded application will turn to
zombie thread and the application will eventually run out of
memory.

issues. Fixed the same to resolve this issue.
