site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Looks like a double panic to me. The first panic is significant not the second one.

Check out whatever function '0x002302EC' is in this kernel, as it is being passed in a NULL pointer. Can anyone explain what mulckPatch_eieio is and what might cause a panic to occur within it? We have a socket layer NKE that exhibits a problem related to it. On the first run of a particular third party application, providing it's never been run before on the machine, on 10.3.x systems, we see a panic. It's difficult to reproduce and only seems to occur in this one obscure instance. Our NKE intercepts the connect() and puts it on hold temporarily, It then allows the connect to proceed normally. But then things go boom. It never happens again with the app. We have never seen it happen anywhere else.
