[OpenAFS] Re: Solaris 10 SPARC hang on shutdown

Hey I'm just passing along what I know. You don't have to take my word for anything. I would rather you or Andrew talk to the kernel guy at Oracle. I asked our Solaris admin (I don't open tickets with Oracle) if he could arrange such a thing. He said the only way he can communicate with them is though their ticketing system.

Oracle holds AFS is not doing the right thing. Sun's reboot kills all user processes successfully except afsd. Oracle says that the afsd's are not user processes that never exit, they are really kernel threads and not user processes at all.
