Passive data connection stuck in CLOSE_WAIT.
--------------------------------------------
Key: FTPSERVER-303
URL: https://issues.apache.org/jira/browse/FTPSERVER-303
Project: FtpServer
Issue Type: Bug
Components: Core
Affects Versions: 1.0.1, 1.0.0
Reporter: Alberto Vazquez
We are using a week old snapshot from Ftpserver (it seems a bit newer than
the 1.0.1 freeze). One of our clients reported that the data connection was
being kept open for a long time ... They are using a propietary client its
name I cannot remember and it was an SSL data connection in passive mode.
After checking this using a windows Filezilla client and a Linux server
running ftpserver (on top of Sun Java Application Server 9) we noticed that the
FTP Server had several sockets in CLOSE_WAIT state. At the client side, the
state was FIN_WAIT_2.
To my mind , this could be related with the Socket leaking bug that was
previously reported with SSL passive connections or its workaround although it
might be SJAS fault or-who-knows. Since we don't have a linux machine
available for testing I don't know what the real problem is.
