Issue/Introduction

We discovered the following issue regarding file transfers.

In our test scenario, several randomly generated files have to be transferred between a Windows Agent 12.2.10 and a Unix Agent 21.0.2 via a TLS Gateway 21.0.2.
Windows 12.2.9 <===> TLS-GW 21.0.2 <===> Unix 21.0.2

The files can be successfully transferred from Unix to Windows. 
Though, there are job errors on the opposite direction (Windows to Unix). 
The error message on the job is: 

2022-03-17 17:22:59 - U00012129 Connection opened from non-TLS Agent '<v12_agent>' to TLS Agent '<v21_Agent>' via Gateway '<TLS_GATEWAY>(10.20.30.400:02223)'. 
2022-03-17 17:23:00 - U00011124 Selection started with filter 'C:\Automic\temp\out/2.tst' ...
2022-03-17 17:23:00 - U00011125 'C:\Automic\temp\out\2.tst'
2022-03-17 17:23:00 - U00011126 Files selected: '1'.
2022-03-17 17:23:00 - U00011409 FT '1189791525': File Transfer has ended abnormally.

The error occurs randomly. Some (not many, but a few) file transfers from Windows to Solaris are working. Mostly, the jobs are stopping with the mentioned error.
