As a wild guess: looks like your application is doing fork and exec.
You might try to add then --trace-children=yes
(and possibly if needed you should use --trace-children-skip=...... if tracing
all children is too much).
Otherwise, try first with a very simple standalone program
e.g. something like:
for (int i = 0; i < 1000; i++)
printf ("hello world %d\n", i);
see if that works, and compare the debug trace of the very simple working
case with the more complex non working case.
