DocuSign Insight - Why does LTN stop working?

Issue

When trying to access LTN, the site will not come up. A restart will help but the issue occurs again. When you look at the tomcat logs for LTN, you see the following error:

28-May-2019 12:45:27.134 SEVERE [19] org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run Unexpected death of background thread [ContainerBackgroundProcessor[StandardEngine[Catalina]]]
java.lang.OutOfMemoryError: Java heap space

 

Solution

In order to resolve this, increase the heap size (jmx) setting for tomcat from the default 256 to 1024.
