Looking at netstat, you don't seem to have any extreme amounts of sockets open which should lead to file handle problems. You also don't a lot of sockets waiting to be closed. So, it does not look like a TCP/IP stack issue as far as I can tell. In the log file, this seems to be an issue that occurs in MINA, even before we get to do anything with the session in FtpServer. At least that is my guess. To move this further, we need to discuss this with more MINA people over at d...@m.a.o. And for that, we need to be able to show the log. Would you be okay with publishing an anonymous log where we replace IPs? /niklas
