Symptoms

Non-RAC - 112033 or 112027 - SLES11 Linux x86-64 - Veritas 5.1.132.100 ODM Library, Version 2.0

Expdp (running with parallel 4) on 11.2.0.3.3 or 11.2.0.2.7 ODM databases causes the system to be unresponsive, and either the system will crash or it has to be restarted.

CPU waits increase rapidly after expdp is launched and these quickly raises to 50%+

If ODM is not linked and the database is restarted, the issue does not reproduce.
