AIX JOURNAL-BASED BACKUP CAUSES "MISC KERNEL HEAP" MEMORY CONSUMPTION (APAR IC97751)

The "filepath" kernel extension used to monitor file system
change activities allocates kernel heap memory for each file
accessed on the system and keeps that memory until the system is
rebooted. On systems with many files this memory consumption
can cause the system to become very slow. AIX commands become
slow until reboot is done.
This symptom has been seen on a system with more than 30 million
files.

Request is to fix TSM Journal-based backup to support this type of scenarios.

    Thank you for submitting the request. This is a recognized requirement and a solution appears to be desirable.
    There are currently no plans to provide requested function. No IBM commitment is made or implies as to the
    eventual delivery of an acceptable solution.
