1.1.1.1 is the local IP, why is this log being printed crazily, already 2 million entries have been logged.

Is there currently an issue with the cluster? Is everything normal with the display?

At what point did it start to output crazily, and what was done to PD at that time?

| username: 大飞哥online | Original post link

If the cluster is all OK, then increase the log level between them to prevent the disk from filling up quickly.

| username: 像风一样的男子 | Original post link

Is the network between each node stable?

| username: Fly-bird | Original post link

I want to ask, this warning should not affect, right? It’s just that this IP 1.1.1.1 is a bit strange.

| username: ajin0514 | Original post link

It is recommended to increase the log level.

| username: 大飞哥online | Original post link

Warn does not affect, but if there are too many, it will fill up the disk.

| username: 月明星稀 | Original post link

The display is normal.

Have you turned off the firewall?
systemctl stop firewalld;
systemctl disable firewalld;

| username: 大飞哥online | Original post link

This alert doesn’t seem like firewalld either.

What service is it?

Check the configuration file. You must have configured this port; otherwise, it wouldn’t be accessed. TiDB’s default ports do not include 5555. So it should be in the configuration file.

Try systemctl stop firewalld; systemctl disable firewalld;
