Description Corey Welton 2010-06-28 16:52:34 EDT
Description of problem:
Discovered while testing bug 535671

Creating a dynagroup, calculating the group and changing in can result in things failing, or taking A Very Long Time to calculate, even for small numbers.

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

How reproducible:
Not sure yet...

Steps to Reproduce:

Prerequisite:  Assure you have one AS server in inventory.  

1. Create a dynagroup:
resource.type.plugin = JBossAS
resource.type.name = JBossAS Server
2. After created, click "Calculate Groups" button.
3. Create a group alert.  For this one, I chose where active threads > 0
4. Edit this dynagroup to be:
resource.type.name.contains = VM
5. Save
6. Attempt to "Calculate Groups" once again.

Actual results:
Very long delay, if it ever comes back.  

Expected results:

With one server it ought to be pretty fast.  I encountered this with "recursive" checked and without.
