    • IO, Management

    • Hide
      • Configure -XX:MaxDirectMemorySize=16M for server to hit error earlier . E.g. add into JAVA_OPTS of standalone.conf
      • run server
      • Run this reproducer
        loop.sh
        #!/bin/bash
for i in {1..10000}
do
  echo $i
  ${jboss.home}/bin/jboss-cli.sh -c ":reload"
  if [ $? == 1 ]
  then
      break
  fi
done

      Eventually you will get an OutOfMemoryError, very soon if tested without XNIO-345 fix

    Description

      ByteBufferSlicePool is used at two points in the server:

      • BufferPoolService (io subsystem)
      • ManagementHttpServer (domain http server)

      This pool should:

      • whenever possible be static, i.e., be not recreated at every reloaded
      • when not possible, we must use the clean() method added via XNIO-317 and fixed by XNIO-346
