I'm playing around with some of the packet and ofdm examples with the eventual 
goal of streaming udp packets generated by gsrteamer encoding a webcamera. 
Unfortunately, I've been having some difficulty with the examples that I can't 
understand. For example, running the packet_loopback_hier example, it will run 
fine for some period of time (seems to be different amount each run) then it 
stops printing message debugs and spams the console with


header_payload_demux0 - Parser returned #f

Occasionally, the flowchart will crash and stop running.

In the current run I have open, the correlation plot looks good, the transmit 
Time Freq and Constellation Plots are active, and the receive plots are no 
longer updated (probably because nothing is being decoded?)

I've tried looking a the archives to see what causes this problem, but have not 
found a good answer.
