작업 mgr을 통해 메모리가 4kB 및 8kB 단계로 증가하지만 반드시이 순서는 아니지만 관찰되었습니다.Windows 작업 관리자에서 프로세스 메모리가 계속 증가 함을 나타냅니다.
가능한 중복 : Windows Task Manager shows process memory keeps growing even though there are no memory leaks
나는, 시간 예약을 QTimer 개체를 해제하지 않았기 때문에이 발생인지 모르겠습니다. 이 메모리 증가를 멈추는 방법과 그것이 왜 발생하는지에 대한 내 생각이 맞는지 조언 해주십시오.

Qt 코드에는 메모리 누수가 없습니다. 어떻게 감지합니까? 작업 관리자는 메모리 누수를 감지하도록 설계되지 않았습니다. –
