The present invention discloses a method / device for recording program exception information, a device and a computer-readable storage medium. Considering that a microkernel cannot directly write data to a user space, the microkernel in the present application allocates corresponding memory space to each thread in the user space in advance in its own memory. Then, the microkernel can store the acquired exception information of the exception thread in the memory space corresponding to the exception thread, and send the thread number of the exception thread to an exception handling thread in the user space. The exception handling thread can read the exception information from the memory space according to the thread number and record it together with the thread number. Since the exception handling thread only has the read permission of the memory space, it will not affect the security of the microkernel. According to the recorded thread number and exception information, the problem of thread operation abnormality can be analyzed and located to eliminate the problem, thereby improving work efficiency and user experience.
