Guess we'll never really know how this situation came to be considering that:
"altered some settings,unistalled some old plugins ..., fixed bug" but
Truncating means 18140 courses.
Did you reset the time to start to a time earlier than before?
Granted, not fair to compare, but I support a K12 server that has 219 courses and if I re-call correctly before upgrading it from 3.highest to 4.1.highest did a cli script to run backups of all of them (no user and they had been reset as well) ... took 3 hours.

I do wish you luck! ![smile]( "smile")
