GCP Monitoring agent increasing memory usage continuously

Question

I have set up a compute engine instance with a GCP monitoring and logging agent. Since it was installed, memory use has grown by more than 50%. 

Is there a way to halt memory usage and return to the initial memory consumption? More than 3 GB of my 3.75 GB of RAM is used, and more than 2 GB of that is used by this process "Google Fluentd is run using the following command line parameters: /opt/google-fluentd/embedded/bin/ruby -Eascii-8bit:ascii-8bit /usr/sbin/google-fluentd —log /var/log/google-fluentd/google-fluentd.log —daemon /var/run/google-fluentd/goo "

 

Update:

Google-fluentd service restart reduces memory use. However, it is necessary to understand the cause of its increasing memory usage. Is the fluentd service flawed?
