Beyond these fixes, VXML application debugs should be handled by the VXML application
developer because the Cisco Technical Assistance Center has limited resources to analyze the
application flow involved. If you have followed the procedure in this document and the source of
excessive memory usage cannot be found, contact 

 in order to review the

application.

There are several tools available for this, such as VisualVM, JProfiler, and Yourkit. Any of the
profilers that assess VXML applications provide details into which data structures accumulate and
do not release memory, which eventually leads to an OutOfMemory condition.

When garbage collection runs depends on the system load. A general rule is that a high-load
system or a system with a small amount of memory encounters garbage collection often whereas
a low-volume system or one with a large amount of memory runs garbage collection less
frequently.

This is assessed by the Java Virtual Machine (JVM). Any object becomes a candidate for garbage
collection once all references to it are discarded.
