Scan alert log for ANY errors/warnings before the crash. Specifically check for memory shortage, check if virtual memory (swap file) is sufficient. Which process crashed and/or reported the error ?

Linux server, Oracle
We had some core dumps and then the database crashed. It didn't come all the way down. Some processes were still running so we did a shutdown abort (non-prod database) and restarted it. All looks good now.

So far research hasn't yielded any answers about why it crashed. One of the errors is something we haven't seen before. Can anyone shed some light on the following error?

ORA-07445: exception encountered: core dump [dbgtrReserveSpace()+100] [SIGSEGV] [ADDR:0x10] [PC:0x107A73284] [Address not mapped to object] [] We appreciate any help or pointing us in the right direction.
