I have an update on this post. Since I originally posted I have done the following per your suggestions: Added storage Converted all disks to XFS Reduced the size of my Docker image file Replaced the extremely old cache HDD with a new SSD Replaced a fan and moved my server to improve temperatures After making all of these changes, it ran for a week straight without issue. However, last night my dockers crashed again. The Dashboard showed the same CPU and Memory spike. This time I had Fix Common Problems installed and it said I was getting out of memory errors. I have attached the diagnostics I downloaded during the spike last night. Any ideas of what I should try next? tower-diagnostics-20190409-1951.zip

Is V6 when Docker was added? If so, it's been several years. Yes, I was having issues with my docker image filling up, but I was never able to pinpoint the problem. Maybe the issue was resolved with one of my dockers being updated. I'll reduce the docker image back to 20G. I'll try this when I get home. I'm not sure what files it would have on the array. Yes, some of my disks are very old. I've just been replacing the smallest disk whenever I add more storage. I'll work on the cooling. Honestly I've never really paid too much attention to temperature because I've never had problems. I guess I have just been lucky.

So you think if I add storage and move everything to XFS this issue will go away?

This issue started a few weeks ago and it happens every few days. I would notice that automations in my homeassistant docker weren't running. When I'd check, I'd find that none of my dockers were accessible. On the dashboard page of Unraid, the CPU and memory would be spiked. The dockers page of Unraid would not load at all. Forgive me if I'm not describing this correctly or providing the right diagnostic data. This is my first real issue with Unraid in 5 years of use. tower-diagnostics-20190313-0935.zip
