Description
I like using photon OVA image to run low power docker containers (reverse proxy, code editor, etc...). Sometimes, at random, I find that the docker containers are unresponsive. Checking ESXI hypervisor, I discover high disk usage, lower (single core at 100%) CPU usage and (if I'm lucky) errors on the console screen:
I'm using the latest OS 3.0 Revision 2 Update3 photon OS (OVA-hw13_uefi) and built in docker (nothing new installed that was not already on the image, besides the containers to the docker itself).

Research direction
Start with the Photon OS 3.0 Revision 2 Update3 OVA-hw13_uefi image and the reported ESXi console error, then examine how the Docker containers correlate with the high disk usage and single-core CPU usage. Done means identifying a reproducible cause and documenting or fixing the condition that freezes the VM.
