I'm confused by your description: "followed by a restart and then perform
a dump".  You can't dump while the system is up ... and your "restart"
implies (to me) that the system is up.
 
Do you mean:
 
   1) we do a shutdown        (control-A shutdown)
 
   2) we do a ^TC             (transfer control)
 
   3) at ISL prompt we do:  DUMP
 
and then the error you mentioned occurs *DURING THE DUMP* ?
 
If so, I'm stumped too!
 
However, if you mean that the system abort happened during step 1 above
(after ^A SHUTDOWN, but before it was completely "shut"), then that's
different, and a dump would be interesting to look at.  Or, if you mean
that you can't restart the machine at all, because the bootup
(START NORECOVERY) results in a system abort ... that's different too!
 
thanks,
