I'm using the Valgrind's massif tool to measure the heap allocation of my application. with the valgrind, the application fails to connect to the DB2 with the below error:
SQL1366N A security plug-in "IBMOSauthclient" processing error occurred on the client. Reason code = "7".
Without the valgrind the application runs fine with connection the the DB2.
valgrind version: valgrind-3.5.0
