ERROR when taking an export using EXPDP

Question

Hi There,
I am receiving the following error when perform the scheduled nightly backup. The strange thing is the production instance has the same setup and it is not having this problem. The following parameters (memory_target, memory_max_target and streams_pool_size) are not being used in the production and non-production database base. They are all set to "0".
Processing object type DATABASE_EXPORT/SCHEMA/TABLE/TABLE_DATA
UDE-04031: operation generated ORACLE error 4031
