Here’s the explanation for the reported behavior:

ADM snapshot agent :It should be running only in one node in multinode environment. Refer the below PDN help for more detail in this regard.

UpdateAdaptiveModels agent : It should be run on all the nodes.

Pega 7 keeps a local cache of scoring models. The model update frequency is implemented by periodically triggering the UpdateAdaptiveModels agent . Below PDN help describes the details on the agent.

UpdateAdaptiveModels agent governs how often the client nodes go to the adaptive server to get the most up to date model.

The default setting is 30 seconds, but if this leads to too much network traffic it can certainly be set to a higher value. It should be on on all nodes, without it, the nodes will not get updated models.
