1. Noticed an intriguing thing. 2. I was believing that the exception "Error reading data from connection" was being raised when the RAM or Processor is highly stressed on executing a query / stored procedure. Hence I modified such executions as under:
(a) instead of fetching all records in one batch, I was fetching the records in small batches using something like 'select first BATCH_SIZE skip BATCH_SIZE * BATCH_COUNT from ...' in a loop. (b) dropped some fields to be fetched. 3. After some time I started to get the exception again, and all the time (DMP files + Database URL shared), despite the modifications at Para 2(a) and 2(b) above. 4. Today I executed the stored procedure with settings to get fetch all the records in a single batch and with all the fields, and there are no exception raised. While Execution as per Para 2(a) and (b) still always raises the exception.
