OS Process modeling/monitoring exhibiting strange behavior

[rak]

Modeling a device running monitored processes yields an alternating result each time the device is modeled. While the OSProcess RRD graphs are created, performance data is not collected on an ongoing basis.

To see this in action:

• Go to raklap
• Go to the OS tab on the raklap device
• Note the OS Processes
• Model raklap
• Note the OS Processes
• Model again and see the OS processes

we saw some issues like this in austin last week

(In [9565]) * fixes #2960

• some objects don't have an id until *after* they are created
• remove these created objects from the list of items that should be deleted

I get the following stack trace coming back to zenmodeler from zenhub after applying changeset r9566. This happens whether or not the device currently has any processes.
