I meet this bug again, No process is using port 7590, but
mind scan said
Port 7590 already in use. Then I wrote a simple c program to bind with 7590, it still failed. Rebooting docker can’t solve it but after reboot the system, the port is clear. I guess it’s a bug of the system.
We will still try to figure out what’s happened but a quick workaround is rebooting the system if anyone meets this problem again.
