8839.0. "Inst fault on 8400" by HYDRA::MARSON (Barry Marson (Software Partner Engineering - SPE) MRO1-2/K5) Fri Feb 14 1997 14:56

    I received the following error message on my AS8400 running DUNIX 4.0a
    with the V3.8 CDROM latest firmware.  The processors are 300 Mhz EV5's
    
    It occured several hundred times, then stopped.
    
    
    inst fault=opdec pid=801 <sybase_iq.11.1.0> pc=0x11ffb43bc ps=0x8 inst=0x0
    
    
    Any help is most appreciated.
    
    thx,

    Barry,
    
    It tells you that you're trying to execute something on your
    stack -- note the pc is a stack address. That instruction would
    appear to be a 0, that is a halt instruction.
    
    sybase_iq.11.1.0 should be dropping core files unless it
    catches the SIGILL generate and longjmps out of trouble.
    But something is doing a wild jump into the stack.
    Got any corrupted dispatch tables, object methods or the
    like?

Or maybe jmp_buf's?  (I.e., did someone say "Sybase"?  See note 8792...  ;-)
