This is actually PK65405. We ran into it as well.

Coincidentally, I was chasing up exactly the same symptom just last week and
came up with APAR PK71695...could be relevant (and has a testable workaround):
ERROR DESCRIPTION:
The DATACTTIME for the FTP client is not being set properly
for send processing. The result is the timer is not set and
thus will never expire.
ADDTIONAL SYMPTOMS: FTP client session terminate
abruptly after the first EZA1485I message is issued
with the following message:
EZA2590E send error from send_data - EDC5120I Interrupted
function call. (errno2=0x76690291).
FTP Client receives EZA2590E only when TRACE is enabled. When
tracing is disabled, problem does not occur.
LOCAL FIX:
Set DATACTTIME to 0. This disbles the data connection timer.
or
Set PROGRESS to 0. This disables the progress message.
