I don't believe that there's any maximum on widgets (but someone that's more i ntimate with the code base might be able to say different) so as far as I know it doesn't sound like that's the problem.
I would like to make one suggestion though. If you need to use that many different text widgets, there's obviosuly something or somethings that you're trying to display for each page that's similar, but a little bit different. If it was me doing it I'd look at how I could create my own widget that can look at the page that it's on and dipslay what it needs to from that information. That way I could have a single sidebar and a single widget for each widget area, and not replicate them page after page after page... Having that may individual widgets would make it almost imposible if something ever needs to be updated.
