    Hello,

    On a Solaris 8 server, init has recently started
    taking up 50% of the cpu, here's the top output:

       PID USERNAME THR PRI NICE SIZE RES STATE TIME
       CPU COMMAND
      2295 root 1 0 0 2440K 224K cpu/0 873:47
    49.98% init

    there are 2 init proc's running, the one shown above
    is the second one. the parent one, while trussing,
    shows this:

    pause() (sleeping...)
        Received signal #18, SIGCLD, in pause() [caught]
          siginfo: SIGCLD CLD_EXITED pid=2339
    status=0x0000
    pause() Err#4
    EINTR
    waitid(P_ALL, 0, 0xFFBEF2E8, WEXITED|WNOHANG|WNOWAIT)
    = 0
    wait() = 2339
    [0x0000]
    sigprocmask(SIG_BLOCK, 0xFFBEF210, 0x00000000) = 0
    sigprocmask(SIG_UNBLOCK, 0xFFBEF210, 0x00000000) = 0
    waitid(P_ALL, 0, 0xFFBEF2E8, WEXITED|WNOHANG|WNOWAIT)
    = 0
    setcontext(0xFFBEF428)
    pause() (sleeping...)

    while the second one (the one taking up cpu) seems to
    be hung. (related to console hanging as well?).

    not sure what to do, can i issue a kill cmd to the
    second init process which seems to have hanged? or can
    i restart the main init process?

    comments, questions, suggestions appreciated.

    thanks !
