Symptoms

Receiving the following error in Enterprise Manager logs:

ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [kghfrf+154] [PC:
0x4F12EC2] [ADDR:0x1C56E69C] [UNABLE_TO_READ] []~

Current SQL statement for this session shows:
begin MGMT_JOB_ENGINE.get_scheduled_steps(:1, :2, :3, :4); end;


Stack Function shows:
kghfrf ptddrp perdcs peidcs kkxcls kxsClean kxsCloseXsc kksCloseCursor

O/S info shows program: OMS

Changes

The problem is occurring during the cleanup of a shared server process that is already marked dead. It has problems freeing memory associated with a hash table, probably due to a memory corruption.

Looks like forcing the OMS to use dedicated server connections rather than shared servers (MTS) prevents the problem from occurring.
