We get those also but they don't shutdown our DB...This is a DW DB and the issue is a bug with star transformations....

Chris,
This usually means that some piece of code committed a bounds violation, trying to read from or write to memory which it did not own.
HTH,

All, I am about to open a TAR...painfully. Had a database (server?) crash a 2AM. Further sadness, the node/instance that crashed hung the other RAC node/instance...could not pull of the RAC reconfiguration...a whole other issue. One crash leads to another crash/hang :o|)
I would like to get comments on the true meaning of "SIGBUS", "SIGSEGV", "...physical address", "...Address not mapped".
I have always believed these to be Oracle/OS memory related issues?
Thanks in advance,
Chris Marquez Oracle DBA
