Hello, We are using ActiveMQ to deliver JMS messages in a distributed peer environment and there seem to be TCP connections leak issue happening on the server machine
Here are some details, but sorry if I am missing posting something here netstat output on server machine - tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59726 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59035 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:58414 ESTABLISHED netstat output on client machine - tcp 0 0 ::ffff:10.40.205.111:59726 ::ffff:10.5.69.95:8501 ESTABLISHED tcp 0 0 ::ffff:10.40.205.111:59035 ::ffff:10.5.69.95:8501 ESTABLISHED tcp 0 0 ::ffff:10.40.205.111:58414 ::ffff:10.5.69.95:8501 ESTABLISHED After some time, tcp connections on client machine are cleared tcp 0 0 ::ffff:10.40.205.111:59726 ::ffff:10.5.69.95:8501 ESTABLISHED But tcp connnections on server machine remain tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59726 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59035 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:58414 ESTABLISHED And this behavior continues and on server machine keep TCP connections keep growing whereas the client machine do not After about 1 hour on server machine - tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59726 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:59035 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:58414 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:61280 ESTABLISHED tcp 0 0 ::ffff:10.5.69.95:8501 ::ffff:10.40.205.111:64875 ESTABLISHED Rate of this tcp growth is variable and takes few days to reach hundreds of TCP connections and a week or two it gets into thousands before it reaches ulimit on file system and requires a restart of the application Using transport.soTimeout=60000 does not seem to be very useful, could this be a firewall related issue or any TCP tuning parameters that can resolve the issue?
