APAR status
Closed as program error.
Error description
This problem is only seen with C++ programs built on AIX v5 and run on AIX v6 or v7. . The program must repeatedly load and unload libraries that use static constructors during execution, then a stale pointer to freed memory may be used and the application may crash. . DB2 versions prior to DB2 10.1 have experienced this problem appearing as DB2 server hang or crash, with the trap file diagnostics frequently including malloc or initializeXalan functions.
