|
Status: Closed |
THE DB2DIAG.LOG IS FILLING WITH INVALID MEMORY ADDR ERROR MESSAGES. WHEN EXTSHM = ON AND USING MEDIUM PAGE SIZE. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When setting EXTSHM=ON on a 64 bit AIX instance the db2diag.log
gets flooded with error message:
Action Taken : 2009-05-07-16.43.36.788014-240 I2378630885A584
LEVEL:
Error (OS)
PID : 2502884 TID : 1 PROC :
db2ipccm 0
INSTANCE: db2ist1 NODE : 000
FUNCTION: DB2 UDB, SQO Mnemory Management, sqloMemSetPageSize,
probe:100
MESSAGE : ZRC=0x820F0002=-2112946174=SQLO_INV_MEM "Invalid
memory addr"
DIA8561C A invalid memory block was encountered.
CALLED : OS, -, shmctl
OSERR : EINVAL (22) "Invalid argument"
DATA #1 : String, 44 bytes
Failure enabling specified memory page size.
DATA #2 : Logical page size, PD_TYPE_MEM_PAGE_SIZE, 8 bytes

These messages will continue to be logged during less frequent
events - instance start-up (db2start) and database activation -
since it can be an important message for DB2 support in some
cases. |
