I see your argument, but try to see our side. The forum went down, and stayed there. Obvious corruption, caused probably by a networking problem. So that sort of thing is not reproducible, but something similar will occur again sooner or later for sure. So we'd like to understand the mechanism which cause such failures as much as we like to get it fixed. So given the history and symptoms, we'd highly appreciate some hints. Where would you look first, into the database state or contents, or into FUD generated files ?

Here the full text of a typical error log entry:
(index.php) 1100: Table 's' was not locked with LOCK TABLES

u.show_avatars, u.show_im, u.posts_ppg, u.time_zone, u.sig,
