Hello. In short, my problem is as follows. I have a 5-node server, 1 of which is a master. I have a problem only on this master node, it gradually shuts down every few minutes and the system generates the following error (notification condition no_leader has been fixed). There is almost no information about this on the Internet. Can you help me and give me the right direction to determine the cause. Graylog version is 5.2.
If your process is terminating it’s probably generating some logs. Take a look here on your master:
/var/log/graylog-server/server.log
Also double check if you have enough memory and it’s not the OOM killer or something.
