Problem IT38961 Status: Closed

HANG WAITING FOR LATCHES INSERTRANGE__MTABLEWRITERLATCH AND
INSERTRANGE__MCONCURRENTINSERTLATCH

product:
DB2 FOR LUW / DB2FORLUW / B50 - DB2
Problem description:
Two threads hang waiting for latches
SQLO_LT_ibm_cde__data__InsertRange__mTableWriterLatch and
SQLO_LT_ibm_cde__data__InsertRange__mConcurrentInsertLatch. The
problem is a deadlock. (Each thread has one of the latches and
is waiting on the other.) Because this deadlock involves a latch
(rather than a lock), it is not detected by the Db2 deadlock
detector.
