CAN periodic status

Is anyone using the periodic status feature of the jaguars? It looks like it's in the LabVIEW library and BDC-COMM, but not in C++ or Java. I also didn't see it in the jaguar CAN documentation (although I may have missed it).

When I use it, I get the requested status, but I also get the following error reported to the driver's station

Diving into the WPI_CANJaguar_GetStatus, it appears that it is only sometimes is receiving the status, and when it doesn't it throws that error.

I set it up with a rate of 0.1 seconds and read it in a 100ms loop in periodic tasks (see attached pictures). Is anyone else using it?
