I have an AWS EC2 instance running a CentOS 7.7.1908 (systemd 219) with a server application. The server logs quite a lot of information to the system logs (using syslog).
I have recently enabled persistent storage of the system logs using this answer. Since then, the memory consumption of systemd-journald is constantly growing.
After a full day, systemd-journald ends up using more than 250M of RAM.
我做了一个快速测试来确认 Journald RAM 使用量实际上在增长。
