Hi,

your log script sound to me like the analyzer either got into an infinite loop or 
did a segment violation and just died. I would recommend to run the analyzer from 
inside the debugger. When you then get the segment violation, you can inspect the 
stack trace and see where the bad things happen. Since the analyzer works nicely in 
other experiment, I expect that your problem is related to the user code. Maybe it 
happens at the end of the run, but there is a timeout before the crashed process 
gets cleaned from the ODB, that's why you might think that it happens "between" 
runs.

Best regards,

  Stefan
