Hi,

I am creating a Job just reading from an oracle source (500,000 rows) and writing directly in a csv. It given me Timeout error after writng 50,000 lines, when i increased  xms to 512m & xmx to 512g it gives below error message after reading all lines but it took around 2 hours to read all lnes. we have 48 gb RAM in the machine and no other users are there. when i am executing the DB source it's working fine and returning output in some seconds.

Any help will be appreciated.

If you see my earlier mail, i already did the same changes but still it's throwing error after reading all data. 

More important its taking so much time to read the data.
