I had an out of memory error last night at about 3.15AM (Dec 2), which required a restart of the docker system to resolve. Looking at the syslog from 3.13am it *looks* like LMS was taking up a lot of memory and killed off. The dashboard registered at 100% RAM use, but the docker tab, advanced view listed nothing strange on the RAM graph (although it could have dropped before I got there - late in the night and lucky to be up).
I'm no expert here - just hunches and blind guesses. If LMS is periodically eating my RAM, could it be the above setting? Diagnostics attached.
EDIT: Happened again as typing this. Docker tab took a long time to load, and when it did, LMS was at 68% RAM usage, with everything else around 1%. Newer file attached, removed old one.
