Status: Closed |
DEADLATCH DURING A COMPLEX QUERY |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
One thread holds SQLP_LTRN_CHAIN__entry_latch and waits for
SQLD_CHAIN__fullChainLatchNS. The second thread has the latches
in the opposite order. Deadlatch occurs. This is timing
related and does not always occur even with the exact same
query. |
