Did you install graylog via the apt package?

Are there any other errors? I looked up that ‘An I/O error has occurred while writing a response message entity to the container output stream’ error but it seems possibly more of symptom than a cause. Can you share a larger portion of the server.log file?

Can you also tell me a bit about your graylog cluster architecture? Are mongodb and opensearch on the same server? Different server? Are you able to reach both mongodb and opensearch ( curl http://:9200 ) via your graylog server?

Also, do you have the ability to look at historical cpu load on the server? I found several threads here with the exact same error and what i can find is that it seems like more of a timeout than an error, where graylog isn’t able to complete the web request. This thread theorizes about server resources and cpu load [Graylog journal continuously growing up - #7 by mpolitaev](https://community.graylog.org/t/graylog-journal-continuously-growing-up/1817/7) .

Something else that could possibly help is increasing the java heap for graylog-server. The default is 1g but i recommend setting to 2g:

1. edit `/etc/default/graylog-server`
2. modify both `-Xms` and `-Xmx` to be 2g:

3. save file

the below sed command also does the same thing:

```auto
sudo sed 's/-Xmx[0-9]\+g /-Xmx2g /g' /etc/default/graylog-server && sudo sed 's/-Xms[0-9]\+g /-Xms2g /g' /etc/default/graylog-server

```
