I forgot to mention that there's a bug in the server side of the
telemetry that occasionally will crash just like this. It appears that
the crash is happening because the buffer the HAL is passing to
CFDataCreate has become bogus some how, but it happens sporadically, so
I haven't been able to nail it down yet. Sorry for the trouble.

Generally this is working but sometimes I get the System UI hang (with
the mouse continuing to move) - I know this is my bug but I'm
wondering what this might be a symptom of?
In the meantime I've fired up the HALLab to see what going on with the
IO and after running for a little while this happened (I was doing
anything at the time):

Is there a limit to how much data can be captured?
Thanks,
Robert.
