Not sure what the root cause was but, i had to do a uninstall and reinstall to correct the issue. Had to do this 3 times because i kept getting FFL errors during reinstall.

This means that your machine ran out of memory when sorting the domains of your blocking lists. Apparently

is too hefty. On which device did you install Pi-hole?

Have you seen such an out-of-memory error before @jacob.salmela?

I have it running in Pi3 and it's been pulling 3+mil domains for sometime now.
I did a uninstall and reinstall and it started working again. Still pulling 3+ mil domains (2.8 mil after duplicates removed). and not having a issue.
