Issue/Introduction

When running an AdminUI and when trying to login to the Adminui from
browser, the login fails and the AdminUI logs report error :

  Unable to establish administration context.
  Caught unexpected Throwable: java.lang.OutOfMemoryError: Java heap space

In server.log that the JBoss Server has memory problem :

  2019-12-03 10:24:49,222 [ERROR]
  com.ca.siteminder.framework.xps.security.AdministratorRelationship

  (HornetQ-server-HornetQServerImpl::serverUUID=XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX-XXXXXXXX))
  HQ214017: Caught unexpected Throwable: java.lang.OutOfMemoryError: Java heap space

In standalone.conf, the following setting are in place, but the issue
still persists :

  JAVA_OPTS="-Xms1024m -Xmx1536m -XX:MaxMetaspaceSize=256M -Djava.net.preferIPv4Stack=true"

Environment

Environment:

Applicable to all the supported 12.8 and 12.8.x releases.

Cause

It looks the problem is known in the WildFly 8.2.0, as there is a
memory leak.

The AdminUI reports starting fine and shows BufferOverflowException
regularly :

This is fixed in WildFly 10.0.0 (1).

Some people report having fixed the memory leak by setting this
parameter (2)(3).

Resolution

In AdminUI standalone.conf, add

  -Djboss.remoting.pooled-buffers=false

in line :

  JAVA_OPTS="-Xms1024m -Xmx1536m -XX:MaxMetaspaceSize=256M -Djava.net.preferIPv4Stack=true"

and increase the value of Xmx to have this configuration :

  JAVA_OPTS="-Xms1024m -Xmx4096m -XX:MaxMetaspaceSize=256M -Djava.net.preferIPv4Stack=true -Djboss.remoting.pooled-buffers=false"
