We are getting the following error upon uploading an xls sheet with 300 records

There's a 60 mns non-configurable limit for unattended nodes to complete. If this limit is hit you will get the following alert:

"The amount of time allocated for the completion of an unattended activity was insufficient to allow the activity to complete."

if you are seeing an error within the first 10 minutes then your assumption is not accurate enough, and the node is not timing out there should be something else.

This smart service generates a very generic alert that asks you to check the application-server.log for more details, my suggestion is the same, review the application-server.log and pay especial attention to the "Caused by" clauses in the stack trace to determine the root cause.
