WinSCP .NET assembly - Session output gets too big

Question

I am using the WinSCP .NET assembly in order to "monitor" on a FTP server, and download every file that is uploaded to the FTP server.

After leaving my program running all night, the ram usage was over 1gb, and after debugging and checking with profiling programs, it happened because of Session.Output, which is an Enumerable collection of strings, which never gets cleared, and collects everything that happens to this Enumerable instead into a log file. I tried adding log file paths to Session.DebugLogPath and Session.SessionLogPath, which copied the Enumerable into a file, but didn't clear it.

How can I disable / clear the Session.Output?

Since WinSCP 5.7.6, WinSCP .NET assembly holds only the last 1000 lines of the output.

Please upgrade.

Note that the Session.Output is not related to the Session.SessionLogPath or the Session.DebugLogPath. They each log different information.

Ok, thank you! For now I will dispose and reset the session when it reaches 300,000 files, and wait for Version 5.7.6 :) – user5441417 Oct 27 '15 at 15:09
I saw version 5.7.6 is out, but this bug isn't fixed there. Did you postpone it to the next version? – user5441417 Nov 08 '15 at 09:05
@user5441417 No I didn't postpone it. The fix is there. The `Session.Output` never grows over 1000 lines. – Martin Prikryl Nov 09 '15 at 14:44
I see, the Bug 1367 was not in [the WinSCP 5.7.6 version history](https://winscp.net/eng/docs/history?a=5.7.6). I've added it. – Martin Prikryl Nov 09 '15 at 14:53
Which can I use better `SessionLogPath` or `DebugLogPath` ? – PreguntonCojoneroCabrón Nov 17 '17 at 13:49
@PreguntonCojoneroCabrón This is not a discussion forum. If you have a question, please post a separate question. Though you need to explain your use case. – Martin Prikryl Nov 20 '17 at 07:46
do you know the answer and cannot publish here? Post question maybe. – PreguntonCojoneroCabrón Nov 20 '17 at 08:01
