Yeah, if this is some sort of inventory tool, it might be reading every individual file, then doing some work on each file to determine if it matches what it's looking for -- and if it ends up searching the caches, yeah... it'll be doing that for a looooong time.
I'd double-check the configuration to see if you've typo'd the cache filesystems or something. Otherwise, you'll need to start harassing IBM regularly.
