Thanks for the quick response! Interesting to know that the same lack of optimization are in both versions of OMV. I wonder why the 1-core, 512MB board is stable as a rock with release 3 and the 4-core, 1028MB board is so much less stable with OMV4? I'll definitely look at the crontab and rc.local. Thanks for that tip
I'd love to replace it with a real computer, but I'm living in Africa and it will be months before I'm somewhere where I will have access to reasonably priced options.
Given my current constraints, do you have any suggestions about the best way to install OMV3 on my PI3B+ to see if it has the same problems? Thanks!
