pulled the drive and made a backup of all the files at least, checkdisk didn't show anything bad and on a new boot I was able to pull the logs. Never posted these before so I hope this is right.
update: I deleted all docker containers again and started from scratch this time, my problem appears to be resplved but if someone with more knowledge than me feels like looking at the logs for anything abnormal that would be appreciated.
update2: I can reproduce the error by firing up Machinaris an setting it to plot, when I do the web UI goes completely bonkers and the system more or less stops responding until reboot, even if I shut down the Machinaris docker. I'm now getting a specific error:
Warning: file_pib_contents():Only -1 of XXX (the number of bytes changes) written, possible out of free disk space in /user/local/emhttp/plugins/unassigned.devices/include/lib.php on line 75
Final update and solution (so far):
Machinaris is mapped to plot using a ramdisk, this script was interrupted when I switched my cache for some reason so /mnt/ram didn't exist, and the docker container dumped the files to who knows where, causing something that wasn't big enough for the files to fill up nearly instantly. So this is all related to some core directory of the unraid install running out of space and that caused the issues.
