Hi all, After migrating my XE from 2.x to 3.1, I get a bunch of these errors in my logs : "[Statistics storing daemon] ERROR o.h.u.JDBCExceptionReporter - Data truncation: Data too long for column 'XWV_IP' at row 1" I suppose it's a change in the statistics related tables ... What should I do to remove these errors ?
