But I have turned this off, and there is no difference. Also I checked the source to our caml_aligned_mmap function and it is essentially the same as Markus Mottl's version in his comment in that thread (this has been reported in 3.10.1 & 3.10.2). It even includes a reference to that bug, indicating that the version we are using includes this patch. I'd still like to know if anyone can reproduce this case. Rich. -- Richard Jones Red Hat
