Symptoms

You are running an ASM instance in a RAC environment, and the ASM instance crashed with errors:

Exception [type: SIGBUS, Non-existent physical address] [ADDR:0x6AE1E000] [PC:0x3003472530, memset()+96] [flags: 0x0, count: 1]
ORA-07445: exception encountered: core dump [memset()+96] [SIGBUS] [ADDR:0x6AE1E000] [PC:0x3003472530] [Non-existent physical address] []
ORA-00081: address range [0x060000000, 0x060001000) is not readable

The stack trace from the core file shows similar to the following:
