Since the performance registry hive is loading external executable code to publish performance data to consumers—for example, Network Monitor—there might be problems with the loadable modules, such as memory leaks and lock ups.
This can result in low memory conditions for the monitored machine.
As its impossible for us to fix the problematic dlls, other than search for newer version of the program, the only thing we can recommend to the user is to create a Scheduled event that restarts the remote registry service on the monitored machine every 24 hours.
