Description
Short-lived Remote EJB clients configured with jboss-ejb-client.properties calling EJB via SSL causing file descriptor leak on the server side.
Since the clients are short-lived, once the JVM is started it will setup the remote connection and invoke the EJB and then the connection is closed when the JVM finishes. With 2 short lived clients calling the server over and over, it leaks file descriptors on the server side.
Looking in the heap we see a lot of sun.security.ssl.SSLEngineImpl and suspect some issue in xnio or perhaps undertow :
