It looks like multiple messages overlapping each other. Removing 3 characters every 4 bytes in the output produces things which seem vaguely recognizable: <22NNI II A ,,,EISA fff <<2>NMI SS 300 ISAAfff There's a sysctl option which you can tweak to make this less likely to happen, but I am not sure about its name. Our console gurus can help you track it down and tune its value :)
