The only debugging tool I know of is ktrace. But, that only shows the syscalls made by the program, not what the kernel is doing internally. This is why Solaris is so nice - pstack and /usr/proc/bin/* progs can tell you what the kernel itself is doing. Furthermore, the kernel debuggers are only available locally and stop the machine, so I don't think that's an option for daedalus since its in a NOC that none of us have access to. Anyone else have ideas or suggestions? Brian (FirstBrian, that is) or Manoj might have some ideas here. -- justin
