Hello,
We just saw an Ora-7445 pop-up in our alert.log.
Quick search on metalink does not hit any specific bug or note. It does seem to be a first timer in this specific environment.
ORA-07445:exception encountered: core dump [qespccpcsv()+616] [SIGSEGV] [ADDR:0x4] [PC:0x1082D4CE8]..
Entry in the alert.log :
Jan 16, 2018 3:11:39 PM EST Errors in file /u01/app/oracle/diag/rdbms/ocdm/OCDM1/trace/OCDM1_ora_53025.trc
(incident=808588): ORA-07445: exception encountered: core dump [qespccpcsv()+616] [SIGSEGV] [ADDR:0x4] [PC:0x1082D4CE8] [Address not mapped to object] []
Any thoughts on this..?
