Mixing active and passive ftp connections cause errors

Test case:
1: Start uFTP
2: Start an "active ftp" connection (e.g. DOS ftp). Log in and run "dir".
3: Start a "passive ftp" connection (e.g. from linux), log in and run "get" on a large file.
4: While the passive connection is still transferring the file, run "dir" on the "active (DOS) ftp".
This will end/terminate the ongoing "passive ftp" file transfer.
Sometimes there are also a never ending "2 Errno = 11" message.

It seems like I'm experiencing the same problem. My case:

  1. (Window CMD, FTP) Connecion is OK, but when commanding "ls" or "dir", the server is unresponsive, and the client is frozen,
  • 230 Login Ok.
  • ftp> ls
  • 200 connection accepted
  • 150 Accepted data connection
    ----------------> Client is frozen.

=> Is uFTP currently unstable in active mode? I need assistance!!!!!
