and

https://access.redhat.com/solutions/4615361

To rectify:

1) Change WildFly configuration:

add <param name="batch-delay" value="0"/> to <http-connector>, for instance:

<http-connector name="http-connector" socket binding="http"> <param name="batch-delay" value="0"/> </http-connector>

2) Add -Dio.netty.maxDirectMemory=0 to JAVA_OPTS in standalone.bat
