Passive data connections can hang forever and thus block a port
---------------------------------------------------------------
Key: FTPSERVER-293
URL: https://issues.apache.org/jira/browse/FTPSERVER-293
Project: FtpServer
Issue Type: Bug
Components: Core
Affects Versions: 1.0.0
Reporter: Niklas Gustavsson
Assignee: Niklas Gustavsson
Fix For: 1.0.1, 1.1
A socket used for a passive data connection can hang (for example due to a
network error or client misbehavior) causing
org.apache.ftpserver.impl.IODataConnection.transfer() never to return. This
will therefore block that port forever, and in the long run hang the entire
server.
