> 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.
