This type of error is typically a bug.  You will probably need to work directly with Oracle Support.

There are some self-diagnostic steps you can try, before making that call.  I won't quote the whole source, but consider:

ORA-7445 [xxxxxx] [SIGBUS] [OBJECT SPECIFIC HARDWARE ERROR]. This ORA-7445 error can occur with many different functions (in place of xxxxxx). For example, the following alert.log excerpt shows the failing function as ksxmcln.

/u01/app/oracle/admin/prod/bdump/
prod_smon_8201.trc:
ORA-7445: exception encountered:
core dump [ksxmcln()+0] [SIGBUS]
[object specific hardware error]
[6822760] [] []

The important part of this error is the ”object specific hardware error” argument, which indicates that there were insufficient operating system resources to complete the action. The most common resources involved are swap and memory.

To diagnose the cause of an ORA-7445 error, you should first check the operating system error log; for example, in Linux this error log is /var/log/messages. Within the error log, look for information with the same time stamp as the ORA-7445 error (this will be in the alert.log next to the error message).
