Problem

A transfer is failing with the following error in the log:

CFTF01E local file ... creation error 000003E3

What does 000003E3 mean?

Resolution

It's an OS-level error code, indicating that the file couldn't be allocated. Specifically, it's an fopen() call that's failing, so it would be necessary to check at the OS level what's causing the failure (such as an invalid member name or dataset name, permissions issues, etc.).
