  HALT instruction executed? 
 The Question is:
 
System (Alpha 4100A running OpenVMS 7.1) stopped with the following codes:
 
halted CPU 0
 
halt code = 5
 
HALT instruction executed
 
PC = ffffffff80075ee0
 
then a prompt
 
P00&gt;&gt;&gt;
 
at this point, entered "b", system booted and seems okay.
 
What do the codes indicate?
 
 The Answer is:
 
  OpenVMS encountered a HALT request while executing in a privileged
  processor mode, and it halted.
 
  As this appears unexpected, the first order would involve determining
  what is located at ffffffff80075ee0 and how execution arrived at this
  address.  It would also be useful to attempt to force the creation of
  a system crashdump file from the console, should this arise again.
