Description of problem:

The "Applicable Errata" report template fails when run against a large number of hosts. (Approximately 17,000). It runs for about 12 hours, until it finally ends with a "500 Internal Server error". (Maybe that 12 hours is a timeout wall?)

When smaller numbers

Version-Release number of selected component (if applicable):

Red Hat Satellite 6.5.2

How reproducible:
Steps to Reproduce:
1. In the WebUI: "Monitor"->"Report Templates"->"Applicable Errata"
2. In the Hosts Filter, specify a search string to match a large number of hosts. Leave errata filter blank
3. Submit

Actual results:

Small numbers return in reasonable amount of time
Large searches take impossibly long to report

Expected results:

Reports generate or at least complete in reasonable amount of time. (i.e. not erroring after 12 hours of waiting to return)
