Description

In CluserEnvBase, the server ports are scanned in the range of 6671-6680, 20001-20010 and 40001-40010. However, in Linux the default net.ipv4.local_port_range is 32768-65535. So it has a high probability that the client port(the client means the one in internal connection between nodes) may occupy 40001-40010 first, and the server will fail to bind the same port when starting.

The solution is just to decrease the port range to about 10000.
