- start Docker service on a Centos 7 VM with 11GB memory allocated
- from docker-compose, start three containers with mem_limit set to 2048m each, and use docker stats to monitor resource usage
- it ran well for 20 minutes or so, but after around 30 minutes, the “docker stats” command stopped reporting numbers, and I had to reboot the VM to get things back running again.
then 1-3 repeat
Any idea what might have caused this? Any logs I shall check to troubleshoot?
