We have upgraded the Datastage Server from 7.5.1.A to 7.5.3 recently and we started encountering below error:

Code: Select all

Parallel job reports failure (code 139),
Contents of phantom output file =>
22100 Segmentation Fault - core dumped

Job is simply inserts /updates few tables and was working in older version of DS 7.5.1.A,but in latest 7.5.3 version we came across with this.
So any body has faced this kind of issue ever or share some of the view points so that we can sort it out.
Thanks in advance.
