RMAN Error with ORA-07445
Hi. We have a client using RMAN backup utility backing up to Dell Data Domain tape. The below error only occurs in one environment, while the other environment works with no issues. Does anyone have any ideas or can point me in the right direction as to what the issue is? Note, the rman backup script works fine backing up to disk. This error only occurs when backing to Dell Data Domain. In addition, the rman script is the exact same in both the working and non-working environment.
ORA-error stack (07445)
No Events found!

dell data domain tape? you mean virtual tape through VTL emulation on the DD or rather using ddboost protocol over the lan without any tape virtual or not being involved?
If you want someone to mention anything, then show the actual whole error stack not just one single error message but containing the context of the lines before and after as well.
The versions (NW, NW NMDA module, OS) used might also give anyone an indication of what you have in place?
Is it similar to this one, where a core dump occurs? https://support.oracle.com/knowledge/Oracle%20Database%20Products/1061232_1.html I can't access the Oracle KB article myself as I have no Oracle sign-in...

The exact error code and argument on the oracle kb is listed below.
ORA-07445: exception encountered: core dump [strlen()+80] [SIGSEGV] [Address not mapped to object] [0x000000000] [] [] error is consistently reported when executing RMAN backup using the Networker or 3rd Party Backup Software.
The argument number is different than whats on the site. Below is what we get.
ORA-error stack (07445[gsignal()+55]
