* Ralf Peng: > Is threads stable enough in product use of Bind?
It's stable on mainstream architectures. GNU/Linux on i386 and amd64 is fine in general. GNU/Linux on hppa, mips(el), ia64, and others is problematic. The hppa instability could be due to the lack of a stable SMP kernel. The ia64 issues seem to be a genuine BIND 9 issue. Part of the problem is that BIND contains its own set of wrappers for atomic CPU operations, instead of using GCC's intrinsics or libatomicops. Last time I tried to look at this, I couldn't find a clear description of the flavor of atomic instructions required by BIND (which barriers are implied etc.), so it's very difficult to make the change. I can't test on ia64 and sparc, either. The x86-derived architectures are just too forgiving about errors in this area to be useful test cases. _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
