Problem IC81500
|
Status: Closed |
ENGINE TRAP WITH ENTRYCALLBACK AND ATMGETHARDENINGLIST IN THE CALLSTACK |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Under rare conditions, you might experience a trap from
automatic statistics collection processing. Automatic
statistics collection is enabled via the AUTO_RUNSTATS database
configuration parameter. This trap is rare because for it to
occur, a memory allocation error must occur in a specific
codepath. When the trap occurs, it will have functions
entryCallback and atmGetHardeningList in the call stack, for
example:
0 ossDumpStackTraceEx
1 OSSTrapFile::dumpEx
2 sqlo_trce
3 sqloEDUCodeTrapHandler
4 __pthread_mutex_cond_lock
5 entryCallback
6 sqlrlc_foreach
7 atmGetHardeningList
8 atmAPI
9 sqlrr_atm
10 atmAPIEntry
11 sqlerKnownProcedure
This problem was first introduced in DB2 Version 9.7 Fixpack 1. |

| Local Fix: |
Disable AUTO_RUNSTATS, which is an online configurable db cfg
parameter. When disabled, you need to consider performing
statistics collection manually as needed, until automatic
statistics collection can be re-enabled. |
