Symptoms

In a brand new WLS domain with domain with SOA, OSB and JDK1.8, the admin server consumes all memory of the server.

Two JDK8 versions were used but got same issue.

Log files do not show any error or alert.

To help detecting the issue, use the top command showing an increment over the time, specially on column VIRT and column RES:

Where JAVA_HOME must be the same JDK8 used by the WLS process.
