DB2 FOR LUW / DB2FORLUW / A10 - DB2

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.
