how many machines do you have connected?  If you have a lot of machines running the inventory that often can be a bad thing.  The inventory is fired off by a kbot also.  You can see what bots you have by looking in C:\ProgramData\Dell\KACE\kbots_cache

this is the bot to fire off inventory on our system:
<?xml version="1.0" encoding="utf-8" ?>
<kbots xmlns="http://kace.com/Kbots.xsd">
<kbot>

<config name="5.2+ Windows CI/Inventory" type="system" id="4" version="1363195678" description="CI/Inventory for windows agents.">

  <execute disconnected="false" logged_off="true">
  </execute>

</config>
