David Latorre commented on FTPSERVER-260:
-----------------------------------------
Hello John,
Can you provide a test case for this? (JMETER's .jmx files?)
The original message for the exception is: java.io.IOException: An
established connection was aborted by the software in your host machine -
googling around I would say this Error message is thrown from the native layer
(windows) -or at least .NET uses the very same message :-)
Have you checked your firewall/antivirus configuration? It could also be some
issue with MINA's implementation or NIO itself ...

> (The message is in spanish because I am in Spain. I believe the exception in
> english is "Software caused connection abort" but I may be wrong).
> I couldn't find a related bug so as a test I set up a JMeter test rig with a
> Thread Group and a basic (passive) FTP Request (user admin, RETR README.txt).
> Sure enough when I increase the concurrent threads this error starts
> appearing. In fact the error can appear occacionally with a single thread
> downloading many files consecutively.
> I have tried this with the latest versions of both JMeter and FtpServer and
> the error is the same.
