I don't see where it comes from, but you can try this to debug it :
in the crossbar code, add a counter for consecutive "0", when the 
counter reaches 7 or 8 as in your example, print the content of all the 
variables used in crossbar and try to see if one of these has some 
completely weird value  (in normal case when playing music, it's unlikey 
you will get 7 or 8 "0" in a row)
