Could it be that these are created by Netty via Cassandra client driver via akka-persistence-cassandra? You can try to add "ch.qos.logback" % "logback-classic" % "1.1.3" dependency and enable logging in logback.xml for <logger name="com.datastax.driver" level="DEBUG" />
That might show you what the Cassandra driver is doing, e.g. scheduling reconnects or something. /Patrik On Fri, Jul 1, 2016 at 7:59 PM, Yan Pei <yan....@gmail.com> wrote: > We run this application via a scheduler, every three hours.
