Issue:
When sending large file (20 GB) with a JOBF, the job stops working and will not end.

When doing a top on the FT sub process of the agent process (ft-src-<RunID>), CPU is at 0 %, while memory is still occupied.
A strace on the same process shows:
write(8, "P", 1 
...and doesn't move any more.
 
Resolution:
Workaround:
Install v12.1.4 (available) or v12.2.2 (available 28-Feb-2019) of the Agent

Then, within the uc-hostchar-default, set the values for 

FT_ASYNC_QUIT_MAX / FT_ASYNC_QUIT_MIN / FT_ASYNC_QUIT_NUM 
to  20 / 0 / 20 

With these changes, the JOBF for big files will work as well. 
 

Solution:

Update to a fix version listed below or a newer version if available.

 

Fix version:

Component(s): Unix Agent

Automation.Engine v12.1.5
Automation.Engine v12.2.3
Automation.Engine v12.3.0
