I'm fiddling with the import from 3.8.x atm, everything was imported but I'm not able to rebuild the user caches past 30k. It works till 24k-29k (depending on users to process per page) but then it stops it can be resumed but stops shortly after again. All other caches went fine, no errors in log. PHP-mem was set to 256/512/1G but not much difference. Server has 16G ram. We have ~95k users with 900k posts. Rebuild wasn't an issue when I tried with 1.0, could it be that new profile fields cause too much load (we have ~40, userfield_value atm ~3,370,552 ) on userdata? I guess theres no command-line way to update users? Any other ideas?
