Abstract: Method and apparatus for detecting a hung up and/or slow-running syscall without affecting the performance of the syscall. Before a syscall is started, a time stamp can be created at a memory address that is distinct from memory addresses to be used by the syscall. While a syscall thread handles the syscall operation, a separate monitor thread monitors the time stamp to track the length of time the syscall operation has been running. If the syscall thread operation exceeds a threshold time limit, then a flag can be sent to a network administrator to indicate that the syscall may be hung up and/or slow running.

Abstract translation: 用于检测挂起和/或缓慢运行的系统调用的方法和装置，而不影响系统调用的性能。 在启动系统调用之前，可以在不同于要由系统调用程序使用的内存地址的内存地址上创建时间戳。 当系统调用线程处理系统调用操作时，单独的监视器线程将监视时间戳来跟踪系统调用操作的运行时间。 如果系统调用线程操作超过阈值时间限制，则可以向网络管理员发送一个标志，指示系统调用可能会挂起和/或运行缓慢。
