ElasticBeanstalk + Vaadin + Tomcat

Has anyone experienced degraded performance when running Vaadin on ElasticBeanstalk? I’ve noticed serving my JSP pages works fine but the application can fail to load occasionally. Browser will display a message along the lines of ‘failed to connect to remote server’. Several times I’ve been notified that EB is terminating an instance because it is no longer receiving data.

I’m using ElasticBeanstalk’s Tomcat 8 with Java 8 platform.

64bit Amazon Linux 2017.03 v2.6.0 running Tomcat 8 Java 8

CPU utilization & network in/out seem to be normal when the latency exeeds 60+ seconds.
