ORA-07445, "SIGSEGV", & "address"???

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
