Observing a significant memory leak when running the Matter Server within a Docker container. Over time, the container’s memory usage steadily increases and is not released.
Collecting hourly memory usage statistics for the matter-server process inside the container using the following cron job:
echo "$(date '+%Y-%m-%d %H:%M:%S') $(ps -C matter-server -o %mem,rss --no-headers)" >> /home/x3735943886/script/matter_server_memory.log
