TL;DR: In this paper, the authors present a system to inform a user of the existence of a zombie process by previously executing a necessary process, judging whether the process exists or not and displaying the zombie process in a panel when it exists.
Abstract: PURPOSE:To inform a user of the existence of a zombie process by previously executing a necessary process, judging whether the process exists or not and displaying the zombie process in a panel when it exists CONSTITUTION:When the user executes log-in, a system is shifted to a log-in process, the process of the processing is called and whether the zombie process exists or not is recognized When the zombie process exists, the panel displaying the existence of the zombie process is outputted Here, the unnecessary zombie process is eliminated and therefore the system comes to a regulay available state

TL;DR: In this paper, a background program removal method and an electronic device are described. The method comprises the steps of receiving a background removal instruction and then obtaining all programs in a current task list; searching for all processes of the obtained programs, wherein all the processes include a main process, sub-processes, a zombie process and an orphan process; and closing all the found processes, so that the programs can be thoroughly removed, the system memory can be released, and the system running speed can be increased.

TL;DR: In this paper, the embodiment of the invention discloses a method and device for realizing a distributed lock, which includes the steps of connecting a storage pool through sanlock, and providing the service of the distributed lock.
Abstract: The embodiment of the invention discloses a method and device for realizing a distributed lock. The method includes the steps of connecting a storage pool through sanlock, and providing the service of the distributed lock; when the storage pool has problems, invoking a fence mechanism through the sanlock, and clearing the process of used resources in the storage pool; clearing the process of resources, used by the sanlock itself, in the storage pool. The method and device for realizing a distributed lock avoid the process jam caused by the problem of basic storage and the zombie process caused by service restart, and solve the problem of the incomplete fence mechanism of the sanlock after the occurrence of the problem of the storage pool.

TL;DR: In this paper, a standby system sub-system which has started the same program as that of an active system sub system is started in background processing by using a CPU core in a standby status and a main storage area, and whether or not the standby system is put in a consistent status that any adverse influence is not generated even after a terminal performs cleanup is confirmed.
Abstract: PROBLEM TO BE SOLVED: To safely achieve the cleanup of a main storage area in which unauthorized data are stored due to memory leak or zombie process or the like without depending on programming language, or imposing any excessive load on one CPU. SOLUTION: When memory usage exceeds a threshold, a standby system sub-system which has started the same program as that of an active system sub-system is started in background processing by using a CPU core in a standby status and a main storage area, and whether or not the standby system sub-system is put in a consistent status that any adverse influence is not generated even after a terminal performs cleanup is confirmed, and the main storage area of the standby system sub-system is used from the active system sub-system, and the standby system sub-system is used as the active system sub-system so that it can seem that the cleanup of the main storage have been quickly and safely achieved from the point of view of a user.

TL;DR: In this article, a system and method is provided for using a kernel exit routine, performed when a parent process exits, to efficiently remove zombie child processes. But, it does not address the problem of removing the parent process when the child process is flagged indicating that the original parent process has already exited.
Abstract: A system and method is provided for using a kernel exit routine, performed when a parent process exits, to efficiently remove zombie child processes. The kernel exit routine also re-parents active child processes to a standard system process, such as the init process. When the kernel exit routine re-parents the active child process to the init process, the child process is flagged indicating that the child's original parent process has already exited. A kernel routine, such as the swapper process, periodically cleans up flagged processes that have exited. In this manner, although active child processes are still re-parented to init, the init process is no longer burdened with the task of waiting on such processes when they exit.
