Insufficient memory to execute a report

<div>I'm using <span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">Birt 4.4.0 and </span><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">calling a Java class to run the reports. </span>The application is <span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">deployed in Tomcat </span><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">and the sql statement returns not more than 100 lines but I'm getting </span><em>There is insufficient memory to execute this report</em> error.</div>

<div>I tried to increase both <span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">heap space and permGen</span> memory on catalina.bat file by <em>-Xms1024m -Xmx4096m -XX:MaxPermSize=512m </em>but no luck.</div>

<div>Any ideas?</div>

<p>How are you calling the Java class to run the report?</p>
<p>Can you provide your full JAVA_OPTS setting from the catalina.bat?</p>
<p> </p>
<p>Are you able to generate the exact same report from the BIRT Designer without issue?</p>

Smithdon

<p>Thank you for your reply.</p>

<p>Yes, I can generate exact same report on the viewer. The problem is when it's deployed in tomcat.</p>

<p>Here is the part of catalina.bat where memory is set. Also attached please find full catalina.bat file</p>

<p>Instead of CATALINA_OPTS, try changing the heap and permgen sizes for JAVA_OPTS in catalina.bat and see if it makes a difference.</p>

Smithdon

<div>setting JAVA_OPTS has no difference.</div>

<div>Since Permanent Generation (PermGen) space has been removed in HotSpot for JVM 8, I just upgraded to 8 and now it's working.</div>
