John Hearn updated FTPSERVER-260:
---------------------------------

    Attachment: FTP_LOAD_TEST.jmx

I am attaching the JMeter configuration that I used. Its very simple - just a 
thread group and an FTP request for the default README.txt file.

The server I ran it against was freshly downloaded (1.0.0-M4) with the simplest 
configuration (just a UserManager).

I also tried disactivating the Windows Firewall but it made no difference.

I agree that it smells of some low level problem.

> Under high load I noticed that strange IOExceptions started appearing in the

> java.io.IOException: Se ha anulado una conexión establecida por el software

> (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.
