FIFO (first-in, first-out) is another way of referring to a pipe.

So either the FTP stage's operator failed to read data from a pipe, or there is something wrong with one of the commands in your FTP stage.

The error message yields no more information than this. Your FTP server log may contain more helpful diagnostics.

I am seeing a similar issue. This only happens occasionally on a job, most of the time it works fine. The job would stay in a running status until it was manually stopped. Looking at the FTP logs, there is not much to see but what I was able to find was that the authentication to the FTP server did not go through until the stop request was issued on the parallel job.

Are there any updates to this post?
