Running out of Java™ heap isn't the only cause of a java.lang.OutOfMemoryError. If native memory runs out, OutOfMemoryErrors that your normal debugging techniques won't be able to solve can occur. This article explains what native memory is, how the Java runtime uses it, what running out of it looks like, and how to debug a native OutOfMemoryError on AIX®. A companion article covers the same topics for Linux® and Windows® systems.
