Servers - OS/2 Trap Errors

Applicable to: World-Wide

The following information will be helpful in diagnosing trap errors.

Error Code	Information
0000 0001	See note 7 (Application software error, contact the software vendor's support).
0002	See notes 4, 6, 8, and 9. Install CSDs, run CHKDSK. Replace the defective memory.
0003 0004 0005	See note 7 (Application software error, contact the software vendor's support).
0006 0007 0008	Check the memory. Run CHKDSK. Contact the application software vendor's support.
0009 000A 000B	See note 7 (Application software error, contact the software vendor's support).
000C	If SYS1942 appears, contact the software vendor's support. If Exception in Device... appears, refer to note 4. Run CHKDSK. All other messages: Run CHKDSK and check the memory. If a 113 error appears, see ECA024.
000D	If SYS1943 A Prog... appears, contact the software vendor's support. If Int Proc Error at 0220:3557 appears, set the Token Ring to 16K RAM window, install CSD's. If double trap 000D appears, install the latest CSDs. For all other messages or conditions, contact the software vendor's support.
000E	See note 7 (Application software error, contact the software vendor's support).
0010	Hardware of software error. Run diagnostics to check math coprocessor. If diagnostics find no problem, see note 7 (contact the software vendor's support).

Notes:
1. Memory intensive operating systems such as OS/2, AIX*, or UNIX based operating systems are capable of revealing highly intermittent errors not detected by diagnostics.

2. Highly intermittent errors might go undetected by diagnostics tests. If no error occurs during the test, multiple replacements of memory might be required to resolve the problem.

3. Install all software updates. This applies to applications and operating systems.

4. The enhanced memory adapter (FRU 34F2825) might experience Trap 0002 errors if it does not have diagonal resistors across U21-U24. See ECA042. (The enhanced memory adapter has been redesigned without resistors, so this note might not apply to the computer you are servicing.)

5. Intermittent errors can be caused by outside sources of static, noise, or power.

6. Trap 0002 can be caused by a memory or adapter failure. Read the message details. It might be the system board, system-board memory, or adapter.

7. Trap 000D errors are software errors. The customer should contact the software vendor for possible patches.

8. For 8570 systems, refer to ECA059, ECA051.

9. For 8580-AXX Models, see ECA051 for possible system board replacement to correct Trap 002, NMI, or DOS parity errors.

System Aid Diskette
A system aid diskette is now available for Trap 0002 errors. Dealers can download it from the Technical Advisors Bulletin Board as file TRAP2LOG. The diskette will read NVRAM and indicate which of four possible sources caused the error. The four possible errors and their causes are listed below.

Error Code	Information
110	Usually a system-board memory error. If replacing the memory does not fix the problem, suspect the system board.
111	I/O Channel Check. Any adapter could cause this error, but usually a memory adapter is the cause.
112	Watchdog Timeout. Could be hardware or software. If replacing the system board does not fix the problem, suspect the software.
113	DMA Timeout. Usually a software error, but possibly a hardware failure (system board). If it is a 70-A21 with a 113 error, see ECA056, run CHKDSK. Contact the software vendor for more information. If it is any other system with a 113 error, refer to ECA023. Check the hardware.
