Optimized SQL is not pushdown with data transfer and order by

Hello,

We have an issue to pushdown with data transfer and order by.

We are getting following error, tried changing the pCache to different drive with more 60 GB free space drive and run the only one Dataflow. The Drive space is decreased to  40 GB and stuck after executing some time.

also change the code page related setting but no luck.

(14.1) 06-15-15 08:11:2 (E) (1592:6188) SYS-170106: |Sub data flow DTT_DF_LOAD_NOTFULLTXTI_REP_INET_2|Transform Query_OrderBy-OrderBy5

  Cannot write onto Disk for the file <E:\DSLogs\pCache/bodsdev.hospira.corp__ds_repo_local12/383621Sort27_1592_5>. OS Error: <No

  space left on device>

In the DataFlow we have SQL -> Query -> Query2 -> Data Transfer -> table comparison -> Map-operation -> Target table (Oracle), Attached the DF as well.
