Forms version: 10.1.0.642

Is there a defined/known limit on the # of controls and lookup rules for a single form?  We have a single form with 250+ controls that are populated by 35 lookup rules.  When we recently added four more controls with four more lookup rules we noticed in our testing that the new controls were not being populated.

As a test, we moved the controls and lookup rules to a new form and confirmed they worked.  We have also confirmed that there does not appear to be a latency issue on our network or access to our auxiliary database from which the lookup rules are retrieving data.
