[jira] [Commented] (FTPSERVER-433) Issues with data transfer for explicit SSL connections

    [ https://issues.apache.org/jira/browse/FTPSERVER-433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477730#comment-13477730 ] 

David Latorre commented on FTPSERVER-433:
-----------------------------------------


 I would suspect some bug in FileZilla. For instance,  there is a bug in WinSCP  (or the library it uses for SSL ) where , depending on the file size, the TLS_CLOSE_NOTIFY message is ill-formed.  Java is a bit pick about this, and will throw an Exception in this case. 

  What version of Filezilla are you using? Can you reproduce this problem with every version?   Does this problem arise only for some file contents?  (Write a text file of the same length as this one and with a character repeting itself  as many times as necessary "111111111111111111111111..." and check again ).

> When using the sample configuration with SSL in explicit mode, some clients (e.g. FileZilla) have problems transferring. There is not problems browsing data, but when uploading the transfers cuts out regularly, and the transfer connections must be restarted. Bellow is sample output from the server log and FileZilla log.
