I vaguely remember from setting up bb in localhost and trying to copy my server DB into my local MySQL that PHPMyAdmin wouldn’t take more than 16 Mb when importing. That might well be a setting that can be set somewhere, I don’t know; I can’t find it in its config file, in any case.

Edit: my localhost version of phpMyAdmin says “Max: 16,384KiB” by the import dialog.

To get around this if it is the problem, can you live without 1/3rd of the posts? Then you could delete them in the original database via some query and export the remaining 2/3rds. It might be better to hold out for someone with more database-mojo to come along and see if there’s a non-destructive way.
