As mentioned above, I think if we can investigate why this error is generated, that will be helpful. Currently the code ensures that if the segment already exists, it should retry to create a segment with other name (refer dsm_impl_windows()), so the point of investigation is, why it is not going via that path? I am guessing due to some reason CreateFileMapping() is returning NULL in this case whereas ideally it should return the existing handle with an error ERROR_ALREADY_EXISTS. With Regards, Amit Kapila.
