darth_fader Posted April 26, 2023 Share Posted April 26, 2023 There isn't enough memory allocated to the JVM to process that much data; jasper is failing because it doesn't have the resources needed to fill that report. If this is happening on your local machine, you can increase the memory available to the JVM, but that will be limited by the system you're using (the actual memory available).https://www.messiahpsychoanalyst.org/wikihow/index.php/How_to_Increase_Java_Memory_in_WindowsIf this is happening on JasperServer, you have several options available to address this, but the most straight forward is again to increase the memory available. You can find documentation on the Apache Tomcat website, and here's an example that demonstrates how that's donehttps://helicaltech.com/how-to-configure-jasper-apache-tomcats-java-heap-size/If increasing the memory available the JVM isn't an option, you can look into virtualizers, which can help segment the amount of memory in use - if so just post back, that's a bit more involved than just bumping up the memory settings - https://helicaltech.com/usage-virtualizers-jasperserver/ Link to comment Share on other sites More sharing options...
