Data Load gives OutOfMemory Error

[anuradha-bala]

Data Load from a table with 7 million rows gives error

Internal error. (Connector error: Exception of type 'System.OutOfMemoryException' was thrown. (DirectAccess-4020))

This happens most times but there are times it successfully loads. What is the Reason? How can we ensure it loads each time.

Sometimes it gives the same error even for 1 million rows. 

What memory is the issue here?  Or is it a different connector error ?

The environment in Qlik Cloud. I am looking to load data to .qvds to use in my Data Model and then the Qliksense Dashboard in Cloud.
