Hi All,

We have customer running a report which does not complete for large range of data. Program is defined as Oracle reports and output type is XML

In the concurrent program log,  no error is reported and the program does not enter the post processing phase. After enabling the report debug , got the following error.

Exception in thread "Thread-5" java.lang.OutOfMemoryError: Java heap space
