      When performing the following big query against a virtual db we have setup in this environment, we get an error

      The query is

       bugs.bug_id, classification.name, bugs.cf_internal_whiteboard,
       dev_cond_nak_grouped."value", partner_grouped."value",
       bugs.cf_last_closed, bugs.bug_severity, bugs.cf_qa_whiteboard,
       bugs.short_desc, qe_cond_nak_grouped."value", bugs.priority,

       blocks_grouped.blocked, qa_contact.login_name, reporter.login_name,
       component.name, flag_grouped.flag_full, bugs.delta_ts,

      LIMIT 0,1000000 

      The error the client sees is

      ERROR: TEIID30048 Error reading 24,668
      DETAIL: org.teiid.jdbc.TeiidSQLException: TEIID30048 Error reading 24,668

      This is using the Postgresql ODBC interface or the JDBC interface

      The errors in the log file are quite long so I will attach the whole log file.
