Odd XSP blinking...ever 30 secs it seems to die and reset?

I have two XSP modules hooked up to my Elk M1 system. Neither of them seems to behave as I would expect (I am trying to use them to control Insteon lighting).

Please view this link:

to see the blink rate of the XSP's. It seems to me that about every 30 seconds or so, the blink rate does some very strange things (kinda dies for a few seconds, then seemingly resets and goes normal blinking for another 30 seconds and dies again.....). The first odd blinking occurs at the 27 second mark, then again at 1:08, and then again at 1:48...)

Bear in mind when this video was shot, no one beside me was home (no other motion/zone changes), and my HA system was not performing any actions that would have cause intermintent power draws.

With the Elk powered off, I have measured the databus resistance to be at 78 Ohms (which is about right I think). Additionally, the system (other than the two XSP in question) has behaved flawlessly for over 4 years.

Is this proper blinking? If not, what else can I check to get these XSP's to work correctly?
 
Just the basics... make sure that they're configured correctly (dip switches, etc); and that they're correctly hooked to the data bus, and properly enrolled.
 
Sorry, I should have mentioned earlier:

-Both units are properly addressed (address 1 and 2 per dip switch setting)
-Both units are enrolled and are seen by the M1 system. I have been able to succesfully upload new firmware to both units (the M1 can "talk to them" just fine).
-Each unit is connected via a separate cat 5 cable to a data hub unit (per post #1, this hub is part of the overall databus - with the proper resistance). Neither of these units is on the end of the RS485 data run, so they have no terminating resistors installed.

This is odd blinking....right?
