The high memory settings stopped working around noon today so it made it through the last night and and this morning and then failed. I started things up again tonight and noticed the server load go up to 18 in about 10 or 15 minutes with kswapd0 being the top process which I think is related to virtual memory.
I briefly looked for a way to change the mysql settings in docker without having to do the thing where I do a docker stop, rm, run, but I couldn't find a way.
At some point tomorrow I plan to go back to the low memory settings to see if they continue to work as well as they did yesterday.
