A Linux application reads cyclically data from up to 32 severs by Tcp. After disconnecting of many/ all servers another Linux application could not send data via the network interface by UDP. nf_conntrack_count shows an unexpected high value: net.netfilter.nf_conntrack_count = 30684 What means the number exactly? And what could be reason for so many open connections if no server is connected?
