upper relate limit

Is there an upper limit to the number of rows in the related table? I have a relate that seems to work well when the number f related items is somewhat small, but when there are a larger number of related items, I get an "Unexpected K encountered at location 2" error message. I still testing to see if this situation holds true throughout the application, and to fine turn the pattern, if any.

Just wanted to know if anyone had any additional insight.
