Hi Yokoo, GnuGk should be able to handle way more than concurrent 123 calls when given enough resources. There is no built-in limit to the number of calls. And even when it runs out of file descriptors it shouldn't crash (just give an error message as in your first trace snippet). I would suggest to look at the stacktrace where in the code it crashed.
