Problem IC71734
|
Status: Closed |
IN RARE TIMING SCENARIOS, CLI-LOAD IN DPF MAY CAUSE TRAP WITH INFINITE RECURSION SYMPTOM. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When a CLI-Load is invoked in a DPF environment, in rare timing
scenarios a trap is possible.
The symptom will show either a 'db2lpart' or 'db2lmr' EDU with
infinite recursion in it's StackTrace with repeated entries from
sqluCSerializableSocketTagged::iNext() and
sqluCSerializableSocketTagged::iOpen(), like so:
<StackTrace>

NOTE: The term "CLI-Load" refers to a CLI application that
invokes INSERT with the SQL_ATTR_USE_LOAD_API functionality, not
a CLI application that invokes the db2Load APIs to process a
data file. |
