SCP (file transfer) does not start because your bash cannot find file libgcc_s.so.1. So it may be path issue. Have you checked for the file? It must be included in path.

WinSCP session does not allocate TTY. On some servers it has such impact that some configuration files are not invoked (such as .bashrc). So if you set your path correctly in .bashrc (in way that libgcc_s.so.1 should be found) try to set it in .profile and vice versa.

It was already specified, but that changes nothing.

It wasn't displayed at all, and everything seems to work fine except file transfers (changing file properties works fine, and 'touch' too).

When using SFTP, the error message is displayed at the beginning of the session and I can't continue...

Obviously there is something strange on both sides (WinSCP and your server). However source of the problem is probably your server. I would recommend you to specify /bin/bash shell on SCP tab of login dialog. And if it does not help, try to use SFTP protocol instead SCP.

In the middle of the log, there is error

Connection has been unexpectedly closed. Server sent command exit status 0.

However the session obviously continued after. Was this error ever displayed to you? If it was, what happened next?

I simply can't transfer any file, while i am able to log and to list directories with no problems.
Each time i want to transfer a file to local computer, it fails with return code 137 (if trying to download)... or it says that host hasn't answered for 15 seconds (if trying to upload), or it simply locks on the transfer dialog window, without any way to close it (if trying to upload a 0 bytes file).
Does someone has an idea of the problem ?

Here is a short log => winscp.log (<invalid hyperlink removed by admin>)

Thx for help...
