deadlock detected during oracle expdp
since you have multiple errors I recommend you to do the following:


if you have an old dump inside this directory move it to another place.
execute the following command select * from v$sgastat where pool='streams pool'; and increase STREAMS_POOL_SIZE value.
check open_cursor value and increase it (make sure scope=both when you edit it).


Note: I would recommend leaving step 3 to the end. Try to take a backup before executing it.
