intel_new_memcpy ( __INTEL_NEW_MEMCPY ) problems are related to bad data
ORA-04030: (Kxs-Heap-W,Qesagetnewbuf:Buffer) With Invalid Numeric Data [ID 1321682.1]
Applies to:Oracle Server - Enterprise Edition - Version: 10.2.0.5 and later [Release: 10.2 and later ]
Oracle Server - Enterprise Edition - Version: 10.2.0.1 to 188.8.131.52 [Release: 10.2 to 11.2]
Information in this document applies to any platform.
- And when running a SELECT statement with a UNION, the following error occurs:
ORA-04030: out of process memory when trying to allocate 8176 bytes (kxs-heap-w,qesaGetNewBuf:buffer)
- However, when using a 32-bit client (i.e. on the 32-bit MS-Windows platform), and when issuing the same SELECT with a UNION, the following error occurs.
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [___intel_new_memcpy+2248] [PC:0x293A158] [ADDR:0x8E04000] [UNABLE_TO_READ] 
This is due to unpublished bug 11878443,
Abstract: - LNX: STAR: ORA-07445 [__INTEL_NEW_MEMCPY()+382] [SIGILL]
As per Bug 12428167 - ORA-4030 FOR (KXS-HEAP-W,QESAGETNEWBUF:BUFFER),
Oracle Development have determined that the ORA-4030 arises due to Bug 11878443.
The problem arises due to incorrect handling of an numeric value in a column, where that number is actually INVALID. Once the fix is applied, the same query should report the error ORA-1722 (invalid number).
1. Identify the column with the bad numeric value and UPDATE that column by just multiplying the value by 1, for example: UPDATE TABLE_A SET COL_A = 1*COL_A;
2. Modify the SQL statement and replace UNION with UNION ALL
3. Request a One-Off Back-port for Bug 11878443
4. Upgrade to 184.108.40.206, where the fix for Bug 11878443 is already included.
