In Linux, there is an out of memory killer feature, which will jump out when the system memory is used up and selectively kill some processes to release some memory. I believe that the majority of migrant workers who are engaged in programming on the Linux server have more or less met each other ). A typical scenario is that one day the machine suddenly fails to be pinged, but ssh cannot be connected. The reason is that the sshd process was killed by

The Out of memory (OOM) killer feature in Linux is a final means of ensuring that the system's memory is sufficient, and after exhausting the system memory or swap area, the process that consumes the system's maximum resources can be judged by an algorithm, sending a signal to the process and forcing the process to terminate.In short, the mechanism monitors those processes that consume too much memory, especially those that quickly consume a lot of me

Android memory management is slightly different from Linux. One of them is the introduction of low memory killer.
1. Reason for introduction

Therefore, to speed up running, Android will not immediately kill a program when you exit it, in this way, the program can be s
