Closed as program error.
Error description
The IBM Integration ODBC Extender (IE02) encapsulates the unixODBC driver manager. When there are many instances of message flow threads performing intensive ODBC activity, there can be a performance overhead with the validation of handles that are passed to the driver manager in ODBC calls. If a snapshot of the process threads is taken, similar call stacks to the following may be seen for some of the message flow threads performing ODBC calls: _global_lock_common _mutex_lock mutex_entry __validate_stmt SQLBindParameter
Local fix
NA
