Concurrent connections count not decreased on SSL socket close
--------------------------------------------------------------
Key: FTPSERVER-137
URL: https://issues.apache.org/jira/browse/FTPSERVER-137
Project: FtpServer
Issue Type: Bug
Components: Core
Affects Versions: 1.0-M1
Reporter: Niklas Gustavsson
Assignee: Niklas Gustavsson
Fix For: 1.0-M2
Reported by Jeroen Cranendonk
"I'm trying to setup a ftps server using the latest svn checkout (As in today
:) ).
Things work fine, except when a ftp client (FileZilla in my case) disconnects.
Underneath is a log showing the error/warning that I get on disconnect (using
the disconnect button on filezilla, which I think is a pretty well accepted way
on closing the connection).
When using flashfxp I seem the same thing happening, even when it first sends a
QUIT (added a log for that after the filezilla one, hope the long mail isn't a
problem! :) ).
Now this warning isn't such a big issue, but it seems the 'logout' code isn't
called when this happens.
The result of this is that I run out of logins, for example with 3 'anonymous
logins' (which = 3 simultaneous logins),
I will not be able to log in anymore after three -sequential- logins. And it's
not hanging connections, even if I close the client entirely, and try to
reconnect, I still get 'Response: 421 Maximum login limit has been reached.'
I've even checked with the tcp view tool from sysinternals that there's really
no connections left.
So I think that because of the thrown exception, the code that normally
decreases the login count isn't called, my guess anyways.
Can someone please verify if this is a bug (and possibly fix it? or tell me how
to fix it ;) )."
