I see Niklas and Sai are already helping you out but just in case ... Which version of Apache Ftpserver are you using? We had some issues with passive data transfers ( related to SSL connections). Are you using plain or SSL connections?
As Niklas said, netstat -an report would be of much help. You can of course "mask the ip-addresses" if you want to keep private information private :-) Still, if you saw something like thousands of connections in fin_wait2 status - it is clear that there's a problem somewhere ( In this case, I think you just need to upgrade to latest version). Depending on your FtpServer version, upgrading the Sun jvm to 1.6.12+ version couldalso be a solution for you. 2009/10/8 <a...@safe-mail.net>: > Hi. > > I have an issue with apache FtpServer. > It's set to use passive mode, and it looks like all of the ports are being > used, which stops any new connections from being connected and the whole ftp > server just hangs.
