High non heap memory consumption

After a clean install of WF11CR1 without any configuration changes and startup with standalone.sh we see a high memory usage on the system side (about 800 MB).

Wenn we do the same with WF10Final we see a memory usage of about 210 MB.

Her are the output auf ps aux:

wf11
ke4 1652 14.0 22.1 2863404 801620 pts/3 Sl+ 14:01 0:07 java -D[Standalone] -server -Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m

wf10

The result is, that we can only start 3 instances of wildfly 11 on a 3.75 GB VM. The 4th instance crashes the system. In our real scenario (Wildfly instances in docker containers hosting the REST interface for our application) we see about 1 GB memory consumption per backend node.

The heap and other memory pools not seems to be the reason for this behaviour - see the attached native memory tracking results.
