pcm-memory was found to become a zombie process in the system, consuming a significant amount of CPU resources. At the same time, the time field in top will become abnormal: this machine only has a total of 56 logical cores, so it needs to run for at least 5124519h/56 = 91509h = 3812days, while the startup time of this machine is only 308 days

What could be the reason for this?
