Hi @apacetech,
Check the comments_to_ed column in the articles table of your OJS 2.x journal to make sure it doesn’t have any unexpected/overlong content such as spam. That column should be able to hold quite a bit of content (65,535 characters, give or take depending on your character set configuration and whether your content contains e.g. accents).
