Information in this document applies to any platform.
This problem was observed on a 184.108.40.206 database on a Solaris SPARC 64-bit server.
The only visible symptoms are ORA-7445 errors, resulting in instance crash.
ORA-07445: exception encountered: core dump [kgllkdl()+2916] [SIGSEGV][ADDR:0x4010000000000B0] [PC:0x106458104] [Address not mapped to object] 
PMON (ospid: 10337): terminating the instance due to error 602
Instance terminated by PMON, pid = 10337
The function stack from the primary (initial) error looks like this:
kkslod kglobld kglobpn kglpim kkqsanjo
kkqsadjo <- kkqsbqjg <- kkqspsum <- kkqsedrv <- kkqsrqb
This error is not likely to be repeating, so when the instance restarts, there is not likely to be a recurrence.
You are likely to see this problem if you are using Materialized views and QUERY_REWRITE is TRUE.
