Hi,
we are getting oracle datablock corruption on the SYSTEM tablespace during periods of intense insert / update activity on other tablespaces.
We are running 8.1.6 under Solaris 2.7.
Typical errors in the alert file are ...
--------------------------------------------------------------------
ORA-00602: internalprogramming exception
ORA-07445: exception encountered: core dump [kghsrch()+56][SIGSEGV] [Address
not mapped to object] [4294967288] [] []

Errors in file/u01/app/oracle/admin/FS75TST/udump/fs75tst_ora_7899.trc:
ORA-01578: ORACLE datablock corrupted (file # 1, block # 13968)
ORA-01110: data file 1:'/u02/oradata/FS75TST/FS75TST_system01.dbf'
ORA-00607: Internal error occurred while making a change to a data block
---------------------------------------------------------------------
Changing the UNIX shmmax parameter from 4GB down to 3.5GB seems to have helped.
Any thoughts
