garbage collection not reflected in the nmon

i have my application running on AIX box (configuration given below)
My application does garbage collection pretty well, as such the memory free shows 500 MB - 700 MB freed up in the log statements printed in the application, but the nmon shows the physical space going upwards and does not reflect the garbage collection that was done. What could be the reason ?

Configuration..

RunTargetUnitTests(1)					    BSD General Commands Manual 				     RunTargetUnitTests(1)

NAME
RunTargetUnitTests -- run unit tests for the current target SYNOPSIS
RunTargetUnitTests DESCRIPTION
RunTargetUnitTests examines its environment and runs the unit tests it presumes are present using otest(1). RunTargetUnitTests is intended to be called from a shell script build phase. It expects certain environment variables to be configured from Xcode build settings (see below). RunTargetUnitTests will run tests for all built architectures appropriate for the machine running the tests. ENVIRONMENT
ARCHS The architectures the tests were built for; when tests are run, they will be run once per architecture. If unspecified, tests are run for the architecture returned by arch(1). DEVELOPER_DIR The Xcode folder, e.g. "/Developer". If unspecified the value for SYSTEM_DEVELOPER_DIR will be used, or "/Developer" if that also is unspecified. BUILT_PRODUCTS_DIR The directory containing built products; when tests are run, this is specified in DYLD_FRAMEWORK_PATH. If unspecified tests are run from the current working directory with no DYLD_FRAMEWORK_PATH. FULL_PRODUCT_NAME The full name of the built product, including its wrapper extension if any. GCC_ENABLE_OBJC_GC Whether or not the test bundle was compiled with Objective-C garbage collection enabled. Possible values are unsupported, supported, and required. If not set, defaults to unsupported, which will run otest(1) with Objective-C garbage collection disabled. NATIVE_ARCH_ACTUAL The architecture of the machine running the tests, used to determine for which architectures tests can be run. If unspecified, defaults to the architecture returned by arch(1). OTEST The path to the otest command line tool; defaults to /Developer/Tools/otest. TEST_AFTER_BUILD Set to YES to run tests, any other value will prevent test execution. FILES
/Developer/Tools/RunTargetUnitTests The script used to run tests from a shell script build phase. /Developer/Tools/otest The OCUnit test rig. SEE ALSO
