Issue Details:

1. When I'm extracting the data from the SFDC object(task) using Informatica, my Session fails after extracting 245824 records.(Task Object).

2. Earlier I didn't get this error. When I run the same mapping before 2 days It was ran successfully, since last two days i'm getting this error. I haven't done any modification in my mapping, I just run the same mapping before and now.

3. Even when I'm trying to extract the data by removing all the transformations and putting filter transformation for the false condition in the mapping, then also my session getting failed after extracting 245824 records(Task Object).

4. I'm not getting these type of errors from other SFDC objects.
