"description": "Equivalent to: cat /proc/sys/kernel/pid_max or cat /proc/sys/kernel/threads-max, It is often used to analyze unlimited fork threads caused by user program bugs. For example, the JVM has been creating threads or thread pools without releasing them. Note: the upper limit of fork thread is controlled by pid_max and threads-max impact. When the upper limit is reached, any client trying to connect to any protocol listening service (TCP or SSH or HTTP) cannot respond, and an error is reported, such as fork: cannot allocate memory. For the principle, please refer to the kernel source code: https://github.com/torvalds/linux/blob/v3.10/include/linux/thread_info.h, See experience with tears in a production env: https://blogs.wl4g.com/archives/2019",
