Siyao Meng commented on HDDS-7374:
----------------------------------
Hi [~jyosin], I can't repro this in a CDP env as well. A cluster has been up
and running fine for 4 days so far.
Are you running this docker compose cluster on macOS? If so can you check you
have sufficient memory for the VM (that hosts the containers) it is using? It
used to crash instances as well when I gave Docker only 6 GB memory.
