Multiple instances created in provisioning script

[Dan Morphis]

I'm trying to ensure a WANPPPConnection instance exists. Per the docs I
should be able to use this:
log('Creating WANPPPInstance (if necessary)');
declare("InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnection.*",
null, {path: 1});

However, when I have that in my script, dozens of instances get created,
and then the script faults with:
Channel has faulted; channel="Provision" retries=0
faultCode="endless_cycle" faultMessage="The provision seems to be repeating
indefinitely"

InternetGatewayDevice.WANDevice.1.WANConnectionDevice.1.WANPPPConnectionNumberOfEntries
 61

Those 60 instances (1 pre-existing) were created before I could kill the
cwmp process :)
Here is a snippet from the log:
