[CLOSED] Communication link failure Error

July 16, 2020, 07:29 AM

Hi,

We are using iWay DataMigrator version 8205.
We have a Main flow that runs other flows and sub-flows and this flow will run on every night.
In one of the Data flow, we are joining(inner) multiple source tables as below.

((SELECT Columns FROM T5 ) T7
INNER JOIN
(SELECT Columns FROM
((( T1 INNER JOIN T2 ON T1.Column = T2.Column)
INNER JOIN T3 ON T1.Column = T3.Column )
INNER JOIN T4 ON T1.Column = T4.Column )
) T6
ON T7.Column = T6.Column
)

In the night process, We are getting the below error in one of the Data flow. Previously it worked fine. But now we got this error in both Stating and Production loads. If I run that data flow separately, I'm not getting the error and the data loaded correctly.

Even I tried to run only this data flow from the main flow, I'm not getting the error. And I'm unable to reproduce the below error.

Can anyone please help me resolve this error.
I think we are getting error in the second table group T6. for first table T7, we are getting 134239 records which is correct.
