Our shop has several jobs that are running on a z/OS system in which we are transfering data to an FTP server. Other than a difference in file names being transfered, the FTP script is virtually the same. Unfortunately, we are having a problem with one specific job. When attempting to log onto the FTP server (via port 987) using TLS, the step fails with a Error code of 410, the exact message reads:
"FC0846 authServer: secure_socket_init failed with rc = 410 (SSL message format is incorrect)"
The other jobs work with no issues, and to make matters work, this particular job only fails about half the time.
If it was happening all the time, I would assume something was wrong with the script, but with it being intermettent, I am perplexed.
I searched IBM and found some info on SSL message issues, but it was specifically addressing usage of port 990.
