You need to find the trace file in your udump destination.  Reading it may
give you some idea what was executing when this happened.  SIGBUS is an
operating system message associated with invalid memory addresses.  It is
likely that you will have to file an SR with Oracle if you are getting these
on a regular basis.  If you find this is a problem in a background process
you might consider relinking the ORACLE HOME.  Btw if it is a background
process dumping core look in bdump not udump.
