Tirupathi Mangalarapu Posted November 7, 2018 Share Posted November 7, 2018 It looks like your server ran out of Heap space. You can increase the heap size to fix the issue but I would strongly recommend you read this threads https://community.jaspersoft.com/wiki/general-discussion-jvm-memory-allocation-jasperreports-serverhttps://community.jaspersoft.com/documentation/tibco-jasperreports-server-installation-guide/v71/setting-jvm-options-application-0 Link to comment Share on other sites More sharing options...
