Error: "No more memory is available: 5000000 objects of size 1 requested"

I have a protocol that reads data out of a file, checks various values against different database tables, and adds data when it is not found in the database.  The protocol is set up to execute all of the SQL for a file as a single transaction, so if an error is found, all database changes can be rolled-back.  On larger files, I will receive the error below on random SQL Select components after running for a while.  None of the select statements retrieve more than a single column from a single row.  Is Pipeline Pilot caching the results of every SQL query in memory for a single transaction?  Is it possible to clear this cache after each record completes pipeline?  We are using Pipeline Pilot 8.0.  Thanks for the help.
