Problem IC96281
|
Status: Closed |
ABEND POSSIBLE IN CLI_SQLDISCONNECT WITH > 512 DATABASE HANDLES ALLOCATED IN MULTITHREAD ENVIRONMENT |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
When a multithreaded CLI application has over 512 database
handles for one environment handle, then DB2 CLI code
reallocates an internal structure.
There is a very small timing window that when a SQLDisconnect (
which calls CLI_sqlDisconnect ) is invoked as this threshold is
reached, stale memory can be referenced, leading to a crash of
the application.
CLI_sqlDisconnect will be the crashing function. |
