I think you are trying to set the system property after Log4j has been initialized. The Spring
configuration file is probably not the best place to do this.

Where to do this depends on the web container you are using. In Tomcat for example you would
specify system properties in this file: {{$\{TOMCAT_HOME}\conf\catalina.properties}}. For
other web containers please consult the container docs.

Instead of using system properties, the property can also be specified in a file named {{log4j2.component.properties}}
by including this file in the classpath of the application.

> JVM getting Out of memory. when I see the heapdump analysis I found 93% of memory occupied
by AsyncLogger's RingBuffer. we have total of 5 AsyncLoggers in our applications each having
default buffer size.
