I've spent some more time investigating this and cannot track down what is occurring (or causing the problem). I compared all of the changes in the plugin from 1.6.3 to 2.1, and nothing jumps out that would cause this type of issue. Some additional questions for you:

Did you just downgrade the RFXCOM plugin, or did you revert back to running Indigo Server 6.1? I ask because we did update the version of the python serial library used from 6.1 to 7, so I'm wondering if that might be related to the problem. If you only downgraded the plugin then that won't be related.

Is it consistently the same 2 sensors that have the problem?
If so, what specific model are those sensors (and do you have the same model of sensors that aren't seeing the problem)?
Once the problem occurs, if you unplug the RFXCOM from the Mac for 1 minute and plug it back in do the sensors start working?
If not, does it start working if you choose the
Plugins->RFXCOM->Reload menu item?
