Not necessarily a DH issue, but it seems the MySql 5.7 container has some form of memory leak on RHEL based systems (RHEL, Fedora, CentOS) based on the default ulimit. Watching container stats, I watched MySql jump immediately to 100% memory usage, using all the memory in the machine, however setting ulimits in the compose file for the mysql container tamed it down to only use about 200mb instead of 12gb. -The more you know
