<div>This report was running for the last 2 months, and today, I added two more date column to the report....and I had been getting this error ever since.</div>
<div>I have other reports that have similar setup as this one(15 columns, 5 aggregated/computed columns) and they ran fine....this one is not. </div>
<div> </div>
<div>I increase the heapsize in the ini file according to other similar post <a data-ipb='nomediaparse' href='
http://stackoverflow.com/questions/8600972/increasing-heap-space-in-eclipse-java-lang-outofmemoryerror'>http://stackoverflow.com/questions/8600972/increasing-heap-space-in-eclipse-java-lang-outofmemoryerror</a></div>
<div> </div>
<div>but still get the heap error. I even went and change the dataset to "select sysdate from dual" and still get the same error. I restart my PC ... no luck.</div>
<div> </div>
<div>Anything else that I can do to fix this issue ?</div>
<div> </div>
<div>my Birt version is Version: Luna Service Release 1 (4.4.1)</div>
<div>Build id: 20140925-1800</div>
