Problem description: | |
This is a concurrent access issue when one thread is traversing the environment's list of database connections looking for a database connection handle and another is freeing a database connection handle on the list and the memory happens to be returned to the OS. The stack of the crash may looks as follows: db2app64!CLI_sqlDisconnect db2app64!SQLDisconnect2 db2app64!SQLDisconnect ... This APAR adds latching code when traversing the list of database connection handles. | |
