Make sure these settings in config.fpw point to local drives.

TMPFILES drive: Specifies where temporary EDITWORK, SORTWORK, and PROGWORK work files are stored if they have not been specified with any of the other options. Because work files can become very large, specify a location with plenty of free space. For faster performance, especially in a multiuser environment, specify a fast disk (such as a local disk ). Default is the startup directory.

SORTWORK path Specifies where commands such as SORT and INDEX should place work files. Because work files can become up to twice as large as the tables being sorted, specify a location with plenty of free space. For faster performance, especially in a multiuser environment, specify a fast disk (such as a local disk ). Default is the startup directory.
