Trying to do a test upgrade of our board from 3 to 4 and after it passes the system checks, it starts the UTF-8 conversion tool.
Gets to the posts table and never gets any further. I've restarted the tool multiple times and the same thing happens.
We have just over a million posts but I've given it 2+ hours and it never moves beyond that table.
Looking at the actual database in phpMyAdmin, the new x_utf_posts table appears to be full and has the number or records it should.
Any ideas what could be causing it to hang on this table?
