Protocol error?

So, I've just added a 'feature' that allows users on the site I'm developing to update the database.  It works, but about 20 minutes into it working (with only two users) it gives me the errors below.

Any body have any ideas what's up?  I'm confused.  For what it's worth, the bean in question (PSDBBean or whatever it is) isn't the new part.  It's the page that get's rendered with a button that opens the new part, but it's not actually the new part, and it's been running for weeks w/out a problem w/out that....


Thanks.

It repeats itself a few more times at various points (in the same bean, and in a utility class that is used in the bean), and finally gives me one different error (which may be more descriptive) which follows:
