      After deploying the sample WAR attached, invoke:

      wget "http://localhost:1099/leak-test/test-service/getBytes?size=2450000" -O /dev/null

      multiple times.

      Running:

      lsof -p <jboss-pid> | grep pipe | wc -l

      will show growth. For smaller byte sizes, we do not see the leak.

      Hello,

      We have identified a leak that we believe is coming from undertow. Using the Wildlfy 8.1CR, we are able to cause the system to leak system pipes (and java.nio.channels.spi.AbstractSelector$1). This bug causes the system to run out of file handles and the server to stop servicing clients.
