RARE ERROR DURING LOB ACCESS MIGHT CAUSE INSTANCE ABEND IN ossSnprintf | |
product: | |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 | |
Problem description: | |
If a normal but rare error occurs during direct read of LOB data (such as failing to obtain an internal conditional latch during latch contention), the error handling might trap due to an uninitialized internal variable. The trap file will contain a stack trace similar to the following: <StackTrace> -------Frame------ ------Function + Offset------ 0x0900000000014980 strlen + 0x0 0x09000000000082A4 _doprnt + 0x2E24 0x0900000000004678 vsnprintf + 0x158 0x0900000013300778 ossSnprintf + 0x40 0x0900000015365488 sqlbDMSDirectRead + 0xA8 0x09000000150B3D1C sqlbDirectRead + 0x9C 0x09000000150B3BE4 sqldx_diskread + 0x84 0x09000000150B37B8 sqldxReadLobData + 0x20 0x09000000150B4064 sqldxReadLob + 0xF8 | |
