Normally when something goes wrong in the memory allocators, it is because a badly written nif/linked-in driver has written outside the buffer it requested by calling driver/enif_alloc. I would take a deep long look at any native code that you have running and see if you can find any such bugs. If you can reproduce the error, I would attempt to run the same scenario in valgrind as it is quite good at spotting these types of errors. </div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Lukas</div></font></span></div></div></div>
