Subject Re: FtpServer hitting its limit?
Date Fri, 09 Oct 2009 07:55:10 GMT
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.

stops any new connections from being connected and the whole ftp server just hangs. If you
try to connect it just reaches time out.
