I haven't experienced that, but it could be a SMP related issue - I only have UP boxes. I would suspect that this is a bug in libc, but it could be perfectly reasonable code in libc tickling some obscure bug in the sparc64 SMP code. > I don't know if that helps you or is something unrelated, just as little > additional point of information. I suspect that your bug is different to mine - but that said, they symptoms match up enough that it *could* be the same issue. That said, it will be an absolute pain to debug. Hopefully I can debug it and we can make some form of fix. Does anyone have any tips for debugging hard lockups on Sparc? Please note that I *don't* have a monitor for the box and am currently working over a serial console.
