Out of memory error -Native heap exhausted...

Environment :RHEL 6 and Webspshere 7.0.0.23 (ND) Architecture AMD (64 bit) ISSUE: Out of memory error -Native heap exhausted... Note:if you are seeing the footprints of Reflection delegating classloaders. When using Java reflection, if the JVM uses a Java bytecode accessor on the class being reflected, it will use native memory. If there is frequent use of Java reflection, there can be a significant amount of native memory use. See the following page for more detail and instructions on how to limit the native memory use of the Java reflection accessors: Please refer : http://www-01.ibm.com/support/docview.wss?uid=swg21373312 you can analyse the Thread dump for Classloader count. if you are seeing having number of java reflectionn class loader then it would be worth adding to JVM argument: -Dsun.reflect.inflationThreshold=0 Soultion :Setting -Xgc:preferredHeapBase=0x100000000 JVM argument.
