Subject [jira] Commented: (FTPSERVER-334) Read Timed Out Prior to Idle Timeout
Date Thu, 17 Sep 2009 19:54:57 GMT

    [ https://issues.apache.org/jira/browse/FTPSERVER-334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756737#action_12756737
] 

Niklas Gustavsson commented on FTPSERVER-334:
---------------------------------------------

Also in this case, the exception is thrown from the TCP /IP stack, rather than in FtpServer.
In this case, it looks like the client doesn't correctly terminate the socket.

> I receive a read timeout when I attempt to passively ftp a file that is longer than the
idle timeout.  The file makes it to the server in its entirety and then throws a read timeout.
 The input and output sockets need to be kept in sync.  I.e. the input socket shouldn't timeout
if the output socket was used within the idle timeout.  Similarly, the output socket shouldn't
timeout if the input socket was used withing the idle timeout.
