Hi Daniel,
In that case you linked to, we believed the number of containers the user was running caused balena-engine to consume more memory than usual due to the way logging to the dashboard works. This is because the Supervisor uses balena logs, which spawns OS threads that consume memory. At the time, our recommendation was to upgrade the HostOS to 2.53.9+rev1.
Can you tell us if you have many containers running? Are you seeing any memory errors?
