In some examples, if a new channel file or other type of configuration 132 arrives while a counting engine 614 has already generated counts or other statistical data 616, the bounding manager 128 can initiate a second instance of the counting engine 614 that operates according to the new configuration 132 and perform a state transfer from the old instance of the counting engine 614 to the new instance of the counting engine 614. For example, a new agent-specific channel file may arrive that, in combination with previously received global and/or customer channel files, would change how the counting engine 614 counts events or generates other statistical data 616. Rather than terminating the existing instance of the counting engine 614 that was generating statistical data 616 based on an old set of configurations 132 and losing already-generated statistical data 616 from that instance of the counting engine 614, the bounding manager 128 may initiate a second instance of the counting engine 614 that generates statistical data 616 based on the new combination of configurations 132.
