----------------------------------------------------

             Summary: Memory leak in the compiler part of the code in Trafodion
                 Key: TRAFODION-2727
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2727
             Project: Apache Trafodion
          Issue Type: Improvement
          Components: sql-cmp
    Affects Versions: any
            Reporter: Selvaganesan Govindarajan
            Assignee: Selvaganesan Govindarajan
             Fix For: 2.3-incubating


The master executor process like mxosrvr which has the compiler embedded within it, grows in virtual memory overtime.  Trafodion i uses its own memory management via  heap to manage its memory needs during execution.  The embedded compiler is also expected to use this infrastructure to manage its memory needs. However, while executor is being build using this infrastructure from ground up, it was an after thought in case of compiler. Some objects in trafodion mixup both its own heap and system heap while allocating leading to memory leak.
