Unfortunately, all TCP connections are now in the TIME_WAIT state.
bash-4.3 # netstat -a -n | grep TIME_WAIT | wc -l
Is there a way to remove it without rebooting the server?
It works. But why doesn't drop the kernel it automatically?
TCP connections in TIME_WAIT will expire after some time, usually between
10 and 60 seconds after a connection is closed. The timeout depends on
the distance of the remote machine.
Yes, but in my case the connections are not expired after over one hour.
